Curriculum – Number Sense and Numerations
- Investigate (e.g., using a number line, a hundreds carpet, a board game with numbered squares) the idea that quantity is greater when counting forward and less when counting backwards.
- Investigate some concepts of quantity through identifying and comparing sets with more, fewer, or the same number of objects.
- Begin to make use of one-to-one correspondence in counting objects and matching groups of objects.
- Child playing one-on-one with an educator.
- Children playing in pairs.
Players take turns drawing a number/dot/word card from a shuffled pile, building a tower using that many unifix cubes, and placing it on the corresponding number on the game board. Then the players collect all of their towers to see whose tower is taller and by how much.
- Players shuffle the 1 to 10 cards and place them upside down.
- Player 1 selects a card (e.g., 6), reads the number, then builds the corresponding “tower” (in this case, 6 unifix cubes tall), and carefully places that tower on the corresponding number on the game board.
- player 2 then selects a card and does the same.
- This continues until each player has had 5 turns, and all 10 cards have been drawn.
- Players can then collect their towers (e.g., towers 2, 3, 4, 7, and 10) to build one tall tower (e.g., 28 unifix cubes tall).
- The player with the taller tower wins.
Questions to Extend Student Thinking
Ask questions such as:
- How many unifix cubes tall is your tower?
- How many more unifix cubes does your tower need to be the same height as the other player’s tower?
- How many unifix cubes does your tower need to get rid of to be the same height as the other player’s tower?
Once students are familiar with coordinates, an extension: Roll & Build Bingo can be played.
