How Many Am I Hiding?
This game teaches students how to find a missing addend. In this game, partners take turns hiding objects (in school we used Unifix cubes) behind his/her back. For example, each student was given 10 unifix cubes. Players took turns breaking his/her tower of 10 cubes into two parts. One part was hidden while the other partner closed his/her eyes, and the other part remained shown. When the second partner opens his/her eyes, s/he must count how many cubes are not hidden. Using that number, s/he must determine how many cubes the partner is hiding. Some strategies we used for this game included:

Using that number, s/he must determine how many cubes the partner is hiding. Some strategies we used for this game included:
- breaking your own tower of 10 into two parts to match what was not hidden
- counting on from the number of cubes that was not hidden using your fingers
- placing the same number as the part not hidden on a ten frame mat and counting how many empty boxes (how many more) until ten

Collect 20 Together
To play this game, you will need a dice and some counters. You can use pennies, erasers, or any other small object for counters. To play, one partner rolls a dice and collects that number of counters. The second partner rolls and does the same. After each turn, stop and discuss the following questions:
Players continue to take turns rolling and collecting counters until the team has collected 20 altogether.
TIP: In the classroom, we collect our counters on double ten frames, to help students keep track of their counting. It also provides a nice visual for kids to see how many more are needed to get to 20. You can get your own double ten frame by clicking here:

- How many do we have altogether? (add)
- How many more do we need to get to 20? (count on or subtract)
- How can you keep track of the counters we have so far?

Double Compare
(add two single-digit numbers)
We learned how to play the game "Double Compare." You can play at home with a deck of cards, with the face cards removed. Each player flips two cards and finds the sum. The player with the larger sum wins all four cards. Once you have gone through the entire deck, the player who has collected the most cards is the winner. This game is similar to the game, "War" but with two cards and adding.
Hint: Use a number line to help your child start at the larger number then count on.

Skip Counting
During part of our Morning Meeting each day, we discuss the calendar and our schedule. Each month, the cards on the calendar will reflect a particular pattern. In September, we are working on skip counting by 2's. You can help your child practice counting by 2's here:

Unit 3: Numerical Operations
(Feb/March)
Students will know and be able to:
52
- Know that number patterns can grow by any consistent amount.
- See counting forward as a growing pattern and as addition
- See counting backward as a shrinking pattern and as subtraction
- Skip count by 2, 5, and 10.
- Understand that the = sign is a relationship (meaning “the same as”) and not an operation.
- Use a number line to add or subtract
- Use counting on as a strategy for addition
- Use counting backwards as a strategy for subtraction
- Use the “combinations of 10” strategy to solve addition problems (5 + 7 = 5 +5 + 2)
- Use “doubles,” “doubles +1,” “doubles -1” to solve addition problems (8+9= 8+8+1 or 9+9-1)
- Use “number decomposition” to solve addition problems (13-4 can “decompose” as (13-3)-1=9)
- Use models to solve math problems
- Solve word problems (addition and subtraction) and equations (with unknowns in all positions) using 2 or more addends whose sum or difference is less than or equal to 20
- Solve multiple addend problems by using combinations that make ten or doubles.
- Apply associative and commutative properties to addition
- Solve double digit addition problems using concrete models or drawings
- Solve double digit addition problems using strategies based on place value (Adding tens to tens and ones to ones, then add together – 35+17=30+10=40
52
- Given a two-digit number mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used
- Add and subtract multiples of 10 within the range of 10-90 mentally and explain reasoning.
- Understand the = sign to mean “the same as” and determine if equations are true or false (5+3=9) (10+2=9+3)
