Question

Draw a quick picture to show the number 24 then draw a quick picture to show 24 after you have regrouped 1 ten as 10 ones explain how both pictures show the same number 24

Answer 1

Explanation:

Total pink triangles = 24

Let first 10 triangles be a circle

let second ten triangles be a square

⇒ red circle = 10 triangles

⇒blue square = 10 triangles

Remaining triangles = 4

Thus circle+square+4 triangles=10+10+4

=24

Refer the attached figure.
