Build the number using ones and tens
To solve the problem of building the number 11 using ones and tens:
Step 1: Recognize that 11 is comprised of one ten and one additional one.
Step 2: Use a single block to represent a ten (which equals 10 units). This is one ten block.
Step 3: Use a second block to represent a single unit. This is one one block.
In the graphical representation, you will need one block showing a full ten and another single unit block to reach the total of 11. This matches choice 1, where you can see 1 ten represented by one set of ten full units and 1 extra unit.
Therefore, the graphical representation of the number 11 is shown correctly in choice 1.
