Last Class: Math Games!

We met all together today for our last 7th grade math classes of the year.

First students shared their homework, and we finished talking about Problem 1.3, Playing the Multiplication Game. Students decided that the game wasn't fair, because 3/4 of the time the products of 2 dice will be even, whereas only 1/4 of the time the products of 2 dice will be odd.

Then we looked at the game of chance Skunk. Students calculated the chances of rolling two ones (snake eyes!) and of rolling one one, and losing their points in the game. Then we played Skunk, and learned the new game Pico, Fermi, Bagels. Class 7B played some other math games with partners to end the session. Class notes may be downloaded here for class 7A and class 7B.

If you still have outstanding homework, I will be checking in with you to turn it in this week.

I hope everyone has a wonderful summer! Thanks for a great year in math.

Percent Error & How Fair are Games of Chance?

Today we met all together, since MaryBeth and Cory are finished for the year. Tomorrow will be the last 7th grade math class.

Students shared their homework. A number of students did not complete the Roller Coaster homework--it can be found here. If you did not finish the homework, please do it tonight and turn it in tomorrow.

Then we discussed Percent Error, and how it can help you determine how good your estimate is. We found that the closer to 0 the percent error is, the better the estimate. Errors can actually be more than 100% if your estimate was more than twice the actual number.

Students also shared their probability homework from yesterday with others who did the same homework. Then we played two games: the Two Dice Sum Game and the Multiplication Game. Both are games played with two people and a pair of dice. In both cases, we compared the experimental probability (the number of times you win out of the number of times you played) to the theoretical probability (the number of favorable outcomes to the number of total possible outcomes). We discussed the likelihood that the sums would be even or odd in the Two Dice Sum Game, and wondered about the likelihood that the products would be even or odd in the Multiplication Game, to figure out whether it was fair or not. Problem 1.3, Playing the Multiplication Game, can be found here, and class notes may be downloaded for class 7A or class 7B. We will continue working on this game tomorrow.

Probability & Test Corrections

LARGE GROUP
Today students received their quizzes back from last week, and we went over corrections to the problems. Then we talked about two games of chance, Match/No Match and Red & Blue Wins! We reviewed experimental probability and theoretical probability, and making tree diagrams and ordered lists for calculating theoretical probability. Students worked on Problem 1.2, Red & Blue Wins, which you can download here, and figured out whether the game was fair, what the chances were for winning, and how much the school would earn. Class notes may be downloaded here for class 7A or class 7B.

Competing Coasters: Estimation & Percent Error

We all met together today, since Cory is no longer working with small groups. And today we had short classes so that we could go to the Upper El Gold Rush performance. Because the performance went long, the 7B class had a shorter class period than 7A.

Both classes talked about roller coasters they had experienced, in preparation for Physics Day at Six Flags tomorrow. We talked about speed, height, length, and duration, and the relationship between these variables in a roller coaster. The learning goal was to talk about Estimation, and how to judge how good your estimates are, by calculating Percent Error.

To do this, we played the game Coaster Competition on the computer. Here are the rules:

Goal: Choose the superlative coaster. Highest points win!

1. Partners take turns
2. Player A chooses a picture of a roller coaster at www.Joyrides.com.
3. Player A estimates & records their estimate on their Roller Coaster Data handout (which you can download here):
· speed
· height
· track length
· duration
4. Player B chooses a picture of a roller coaster they think will be faster, higher, and longer at Joyrides.
5. Player B estimates & records their estimate on their handout:
· speed
· height
· track length
· duration
6. When both players have made their estimates, they check actual data at www.RCDB.com, an extensive roller coaster database. The search box at the top left allows you to find out the actual measurements for your roller coaster. They record the actual measurements on their handouts.
7. One point each is awarded for the fastest, highest, longest track, and longest duration. The player with the most points win.
8. Next time, Player B goes first, and Player A goes second. Players must choose a new roller coaster every time.

In Class 7A, we had a chance to play the game and talk about how to improve our estimates. We discussed how we can figure out how good our estimates are by calculating the Percent Error with this formula:

Estimation Score = Percent Error = (Estimated amt. - Actual amt./Actual Amount) x 100

Class notes may be downloaded here.

HOMEWORK: CLASS 7A
Play the Coaster Competition game 8 times with someone, going to Joyrides to pick a picture and estimate, find out actual measurements on RCDB, and record your data on the Roller Coaster Data handout.

The calculate the Percent Error of your estimates for one of the variables (speed, height, length, or duration) for each of the 8 rounds, and record the percent error on the Estimation Score Chart handout, which you can download here.

Due Monday, June 7.

HOMEWORK: CLASS 7B
Play the Coaster Competition game 8 times with someone, going to Joyrides to pick a picture and estimate, find out actual measurements on RCDB, and record your data on the Roller Coaster Data handout.

Due Monday, June 7.

Student Self-Assessment

Today students shared their homework, then took an assessment of their learning from the past few weeks. Large group students took a quiz on the Filling & Wrapping work they have been doing with cylinders and prisms, and Small group students took a quiz on the Moving Straight Ahead linear equation work they have been doing with MaryBeth and Cory.

As we finish up the school year, we also want students to assess their own learning in math.

HOMEWORK

Please fill out the online student self-assessment form. Answer the multiple choice questions about learning habits, rating yourself as Emerging (starting to show this behavior), Developing (showing this behavior on a regular basis), or Mastering (almost always shows this behavior). Then answer the 3 reflection questions in full sentences, to be included in the progress report that becomes part of your student record that goes to parents and high schools.

Due Tuesday, June 8.

Math Reflections & Fill'R Up

LARGE GROUP
We shared or worked on homework today, then worked on Math Reflections 3, which is included at the bottom of yesterday's Homework handout, which you can download here. Then we worked on a problem looking at the relationship between volume and scale factor in rectangular prisms. In Stretching & Shrinking, we found that the perimeter of two similar figures changed with the scale factor, but that the area of two similar figures changed with the square of the scale factor. In this problem, using the Purple Prisms Applet, we found that the volume of two similar prisms changes with the cube of the scale factor. Class notes may be downloaded here.

No more math this week. Have a great rest of the week and long weekend!

ACE 3.2: Filling Cylinders and Linear equations

LARGE GROUP
In large group today we did a warm-up identifying prisms and pyramids and solving some measurement problems. We talked about how to find the volume of triangular vs. rectangular prisms, multiplying the area of the Base by the height of the prism. And we also reviewed circles, and found that a little over 3 radius squares fit in the area of a circle.

Then we went over Problem 3.2, in which we compared the volume and surface area of two cylinders, one made of a sheet of paper the long, thin way (Tom), and one made out of the same size paper the short, fat way (Jerry). Students made conjectures about whether the cylinders would have equal volume, then tested to find out. They did the same with surface area. We found that the Jerry cylinder had a larger base circle area, and that the volume ended up being larger than the Tom cylinder, even though the Tom cylinder was taller. We also found that the Jerry cylinder had bigger surface area, because although the curved surfaces were equal, the Base area of Jerry was larger. The problem may be downloaded here, and class notes may be downloaded here.

We don't have another math class until next Monday. Have a great rest of the week!

Volume of Prisms & Linear Function Equations

LARGE GROUP
Students completed a reflection about the ERB, answering these 3 questions:
1. What went well for you?
2. What was difficult?
3. Do you have any questions about any of the math on the test?

Then we discussed Problem 3.1, Filling Fancy Boxes, which you can download here. Student groups made 4 prisms with an increasing number of sides out the same size sheet of paper, with equal height, and compared their volumes and surface areas in different ways. Some groups filled them with unit cubes, others filled them with beans or lentils, and others made measurements and calculations.

We found that the conjecture that the volume increases as the number of sides of the prism increases was correct. Tomorrow we will discuss what happens to the surface area. Class notes may be downloaded here (class 7A, class 7B).

LARGE GROUP HOMEWORK
ACE 3.1 Homework

3D Geometry & Linear Functions

LARGE GROUP
Today the large group finished working on the packaging blocks problem. In the problem, students took 24 cubes and figured out how many different rectangular prisms (boxes) they could make, their dimensions, their surface area, and their volume. They found that long and skinny boxes had big surface areas, whereas short stubby ones that looked more like cubes had smaller surface area, and thus used less paper (more eco-friendly!). We also talked about prisms and pyramids. Class notes may be downloaded here for class 7A and class 7B.

We also talked a bit about exponents and powers, examining patterns in the powers of 10 and powers of 3 with some Montessori materials that illustrate this well. Understanding square and cubic units relies on a good understanding of exponents and powers.

No homework tonight, but students should remember to bring a calculator with them tomorrow for ERB testing.

No math class until Monday; have a great weekend!

SMALL GROUPS
Students met with Cory today to continue work with Linear Functions. They worked on Problem 1.3 from Moving Straight Ahead, and on problems 1-7 on the Skill Sheet on Linear Relationships, which you can download here.

3D Geometry: Nets, Surface Area, and Volume

LARGE GROUP
We talked about 3-dimensional geometry today. First we worked on a problem at a box factory, where Emma had to find all the possible nets (2 dimensional figures that can be folded into a box) that would create a cube; the problem can be downloaded here. Both classes found that there were 11 unique nets that can make cubes. Then we worked on another box problem where a factory wants to find all the possible boxes with volume 24 cubic inches possible. Students were reminded of a couple of formulas:

volume = length x width x height
surface area = 2 (length x width) + 2 (width x height) + 2 (length x height)

Class notes may be downloaded here for class 7A and class 7B.

Please make your corrections to the Unit Test in colored pencil, without erasing or scratching out your original answers.

Due tomorrow, Thursday, May 6.

Standardized Test Taking Skills

BOTH GROUPS
MaryBeth Ventura, our Learning Specialist, taught a lesson on Monday about standardized test taking skills. The ERB tests are not high-stakes criteria based test, but norm-referenced tests, which means results are compared to other students around the country who took the same test, rather than specifically on what the students at this school have been studying. The school uses the results of this test to look at what we cover in the curriculum, for example. Learning how to take standardized tests is a useful skill, since most students will be taking them in the future, for example, college entrance exams.

Students generated the following strategies to feel more prepared and less anxious before and during testing.

Before the test:
Stay calm
Don’t think about it too much
Move a little to get blood moving
Eat for energy (whole grains, protein)
Study—keep up in class
Listen to music on way to school
Self pep-talk/prayer
Get lots of sleep
Practice tests
Have materials ready

During the test:
Stay calm
Take your time/Don’t rush
Read the questions carefully
Read all the choices
Look for key terms
Eliminate obviously wrong answers
Make an educated guess (no penalty for guessing)
Preview whole test to pace yourself
Skip questions you’re stuck on and return if you have time
Look over your answers again at end

We also talked about techniques to reduce anxiety. Positive self-talk is the number one anxiety reducing technique. We also practiced two other techniques: tense & relax, and visualization with cupped eyes.

Finally, we talked about strategies specific to math standardized tests:
1. Read question & instructions carefully
2. Open up right files in your mind
3. Use scratch paper
4. Write down the information and quantities given
5. Write down the question to be answered
6. Draw a picture of the problem
7. Try to put quantities into an equation
(+, -, x, /, proportion)
8. Look for key terms
9. Estimate
10. Rule out & guess

In class on Tuesday we practiced taking a standardized test, and discussed our answers and strategies. Class notes may be downloaded here for class 7A or class 7B.

LARGE GROUP
In class 7A we started working on a 3 dimensional geometry problem using nets, flat figures that can be folded and made into boxes. We reviewed some terms from geometry, including vertex, edge, area, surface area, volume, square, and cube. The problem we will continue working on tomorrow is to determine how many possible nets can make a cube.

No homework tonight for LARGE or SMALL groups.

ACE 4.3 Distributive Property & Subtraction

LARGE GROUP
Today we talked more about the Distributive Property, and found that it works for multiplication over addition, and multiplication over subtraction. Students practiced drawing rectangle representations for expressions showing the Distributive Property. We also learned that when using the Distributive Property, you can write the expression as a product of factors (one or both of which have two terms), which is called factoring the expression, or you can write the expression as a sum of addends (one or both of which might be products), which is called expanding the expression. Students worked on Problem 4.3, The Distributive Property & Subtraction. Class notes may be downloaded here.
