“Combine 6 and 7 by breaking the 7 into 4 and 3, then adding 6 to the 4 to make 10 and then add on the 3 more.” (up to 20)

Unit: Building Number SEnse

This unit focuses on developing and using good number sense and will be continued all year.

Number System: Saying and writing numbers to 100 using the 100 chart - looking at patterns and sequencing of numbers.

Number Relationships: Finding number combinations. Example – combinations for eight 4 + 4, 5 + 3, 2 + 6, 7 + 1, 0 + 8

Addition and Subtraction: Solving combining and separating situations by modeling or acting out.

Some students will be using tools and counting all the objects.

Others will start at a number like 8 and then count on two more or count back two.

Activities to do at home:

COUNT anything and everything
Look at patterns of dots (on dominoes) and identify how they see the dots. Example: 6 dots may be seen as 3 and 3 or 2 and 2 and 2 or 4 and 2.
Look for patterns on the 100 Chart.
Play Chutes and Ladders or another similar board game.
Fill in missing numbers on a 100 chart and talk about how they know what number fits.
