This Week in Math (Oct 30th – Nov 3rd) Counting by Tens From Any Number

This week we are learning strategies for skip counting by ten starting from ANY number less than 100. We have learned a few strategies:

1. Find the number on the Hundred Chart. Follow the column to count on by tens.

2. Draw the number using base ten blocks. Add a ten stick for every extra ten you count.

3. Remember the pattern that when counting by tens the ones place doesn’t change. Example: 12 – 22 – 32 – 42 –> The number always ends in two.

4. Use dimes and coins to help you skip count by tens.

 

Play some games to practice:

This Week in Math (October 23 – 27)

This week we are reviewing REPRESENTING numbers up to 100 in different ways. We can use base ten, ten frames, pictures and more.

In particular, we have learned about Canadian money, using coins as a way to show a number as an amount. Enjoy these fun videos about Canadian coins…

 

Optional IXL tabs to work on include:

O.1Coin values

O.2Count money – up to $1

O.4Equivalent amounts of money – up to $1

 

 

This Week in Math (September 18th)

This week in math we are working on counting numbers by 5’s and 10’s and comparing them using the symbols <,>, = .

Image result for greater than less than rules

For extra practice check out this game! (play option “whole numbers”)

Optional IXL tabs to work on include:

A.1 Skip Counting

A.2 Skip Counting Sequences

A.3 Counting Patterns – up to 100

B.1 Comparing numbers up to 100

 

This Week in Math (March 6th)

This week we are learning how to add two-digit numbers that require REGROUPING.

REGROUPING is what you may have learned as “carrying”. However, in order to understand the concept, we are not simply putting a little bitty one on top of the next column. In REGROUPING, we draw out the numbers using base ten representation and circle when our ones create a “ten”. Then we can count our tens and our ones.

Check out this fantastic teaching video to understand the concept of REGROUPING:

Once you understand the process, it is time for some practice!!!

ADDITION GAME

For Parents: This page gives a detailed explanation of how students learn addition, with good visuals to understand why it is taught a certain way.
