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.

Math Reflections 3 & Units of Measure

LARGE GROUP
Students took a mini-assessment using the terms factors, divisors, product, multiples, and divisible by.

Then students did a Think-Pair-Share on Math Reflections 3, to consolidate what we know about multiplying and dividing integers.

Finally, students brainstormed all the measurement terms they could think of, and in small groups categorized and labeled them as to what they measure. Students thought of measurements for length, area, volume, mass, time, temperature, brightness, sound, earth movement/vibration, power, data storage, etc.

We discussed the metric system, and students learned how to convert from one unit to the other within the metric system, for example, from kilometers to meters. Class notes may be downloaded here for class 7A or class 7B.

LARGE GROUP HOMEWORK
Finish Math Reflections 3, questions 1-3 on page 59.

Finish Metric Conversions handout, which you can download here.

Partner Quiz Corrections

Today both groups met together with Sima. We discussed the Partner Quiz answers. Students practiced standardized test math questions, and some students worked at the Mathwizz web site on addition and multiplication of integers.

Homework: Partner Quiz Corrections

Please look at the problems marked with arrows on the Partner Quiz, and try again. You may use your notes, math book, and help from others. Please make your corrections in colored pencil! I will not accept corrections made in regular pencil, or erasing your work, because it is important to make your thinking before and after visible.

Corrections due Monday, April 12.

ACE 3.1 Intro to Multiplication with Integers

LARGE GROUP
The students considered the following puzzler as a warm up problem. Class 7A should consider this problem further, and both classes should share this with their families!

String Burning Puzzle

You have 2 pieces of string of different, unspecified length, and some matches. Each piece of string takes exactly an hour to burn, but the burn rate is not constant. This means that it could take 59 minutes to burn the first 1⁄4, and 1 minute for the rest. The strings have different burn rates, and of course you don't know the rates anyway. Using only the matches and the strings, measure 45 minutes.

Then we worked on Problem 3.1, Introducing Multiplication of Integers, looking at a number line model to see whether products are positive or negative when we multiply integers together. Some students also worked on Problem 3.2, Multiplication Patterns. We found that like addition, multiplication is commutative. If you switch the position of factors in an equation, the product is still the same.

Algorithms for multiplication students came up with called for multiplying the absolute values of numbers together. When multiplying two positive or two negative numbers, the product will be positive. When multiplying a positive and negative number together, the product will be negative. Class notes may be downloaded here for class 7A or class 7B.
