I can solve problems using knowledge of the composition powers of 10
Show transcript
An understanding of the composition of the powers of 10 supports us when we solve problems.
If we know one-quarter of 1,000 is 250, we know one-quarter of 1,000 thousands (1,000,000) is 250 thousands (250,000)
Just as with smaller numbers, word problems can be represented visually as a bar model.
A bar model supports us to form an equation to then solve.
