We retold the story using the characters. Then we acted out story problems. We worked with the problems orally. Students had to decide if we needed to join or separate to solve the problem. Then they acted the problem out to solve it. My kids love to act out stories and story problems. It gets them more involved than anything else we do. We always act out the story or do enough problems so that everyone gets at least one turn.
We also used a life-size number line to retell the story and to orally solve subtraction problems.
We used a die, snowflakes, and the number line to solve subtraction problems. Students used beaded pipe cleaner counting rods and snowflake counters to solve the problems while students took turn solving the problems on the large number line. In our curriculum we are still solving problems orally and joining and separating without writing out equations.
We reviewed the numbers 11-16 using ten frames and snowflake counters. We filled in one ten frame with 10 snowflake counters. We glued the counters down and talked about how those 10 would not change each time. We practiced counting on and not having to count the first 10 snowflakes each time. We used a die to generate the number we added to the bottom frame. We counted the snowflakes and practiced writing the number in the set. You can get the picture cards and other resources here.
