Building Number Towers with Blocks
Objective
Students will create physical representations of numbers 1-10 using manipulatives to demonstrate number recognition and counting skills.
Materials
- building blocks or counting cubes
- number cards 1-10
- chart paper
- markers
- whiteboard
Hook
Show students a tower of 5 blocks and ask them to count how many blocks they see. Then challenge them to build their own tower with a different number of blocks.
Main Activity
Students work in pairs to draw number cards and build towers using the corresponding number of blocks. They start with numbers 1-5, then progress to 6-10. After building each tower, students walk around the classroom to compare their towers with others who drew the same number card. They practice counting each tower out loud and checking if towers with the same number card have the same height. Students then arrange all towers in order from shortest to tallest, creating a visual number line on the floor.
Discussion Questions
- Which tower is the tallest and which number does it represent?
- What happens to the towers as the numbers get bigger?
- How can you check if your tower has the right number of blocks?
- What do you notice when you compare towers with the same number?
- Which numbers make towers that are easy to count and which ones are harder?
Exit Ticket
Students choose a number card and quickly build a tower with that many blocks, then count aloud to show their tower is correct.
Differentiation
Support: Provide number cards with both numerals and dot patterns, and limit initial practice to numbers 1-5 with teacher guidance for counting.
Extension: Challenge students to build towers for numbers 11-15, or create two towers and determine which number is greater by comparing heights.
