Math Update: Jan 7-10

January 5, 2019 by Kim Sorensen & Rebecca Farley

Happy New Year! I hope you all enjoyed the holiday season and had some time to rest and spend time with those you love. I spent much needed time with friends and family. I am looking forward to the new year and can’t wait to see what is in store for our class!

4th Grade Math: To start of with, I want to encourage everyone to continue working on their math facts! As we progress into some tougher concepts, their math fact knowledge is crucial to be successful.

This week we will be working with multiplicative comparisons. This is recognizing that multiplication can be used to compare. For example, John’s flashlight shines 4 feet. Megan’s flashlight shines 5 times as far as John’s. How far does Megan’s flashlight shine? 5 times as many as 4 is 20, so Megan’s flashlight shines 20 feet. We will look at these problems using T-charts to help keep our information organized. This standard is as much reading comprehension as math computation!

  • Questions to ask your 4th grader this week:
  • What is an example of a multiplicative comparison?
  • What operations do you use when solving multiplicative comparison problems?

IXLs that work with this week’s lessons: D.3

3rd Grade Math:  I want to also encourage 3rd grade to work hard on passing those math facts! The past two weeks, we are averaging about 3 people a day passing a math fact test. It will take us a long time to pass these off if we stay at this rate. Please, Please, if you have any questions about what math fact study looks like at home, please reach out to me, email me or let’s plan a time to meet to help your child be successful.

This week we will be studying the properties of multiplication, identity, zero, commutative, associative, and distributive.

  • Questions to ask your 3rd grader this week:
  • Ask them to define the identity, zero, commutative, associative properties of multiplication. There is a page on the test where they will write out the definitions in their own words and the more chance they have to explain it, the more successful they will be!
