Let's use the triangles as the objects to show how 24 is grouped.
There are 2 figures in the tens place and 4 figures in the ones place.

2 x 10 = 20
4 x 1 = 4
24

Regroup 1 ten as 10 ones

Tens Ones
Δ Δ Δ Δ Δ Δ Δ Δ Δ Δ Δ
Δ Δ Δ Δ

There is 1 figure in the tens place and 14 in the ones place.

1 x 10 = 10
14 x 1 = 14
24

Though each grouping may look different, they all have the same value.
