Building Fluency Using Combinations of 10
Games and activities using cubes, counters and ten frames, carefully sequenced to develop fluency with Combinations of Ten.
[Prior to the lesson the teacher will need to make a bag of 8 pieces of macaroni.] The teacher begins to share the story, "I went to the store to buy some macaroni for our math lesson. Here is one bag that I have made. What do you notice? What do you wonder? The teacher states: "I need 10 pieces of macaroni in a bag. Do you think I have enough? How can we be sure? "
Using macaroni, students model combinations through 10 and record a written expression.
Use cubes to model combinations of ten; explore the different addend pairs, and play a card game to apply their understanding.
Students use ten-frames to model combinations of ten. They explore the different addend pairs, and play a game to apply their understanding.
Students explore multiple ways to make ten with tens frames and drawings, with a final project of a class book.
Students may take as long as they need to answer these problems.
Accommodation: Give the students only half of the problems. Teacher may also allow them to use tools to solve the problems.
