Worked Examples
Worked Example 2
Reading Word Form
Write forty-eight as a number and in expanded form.
- 1Forty is 40 and eight is 8.
- 240 + 8 = 48
Answer: 48; 40 + 8
Common Mistakes to Watch For
Writing every word as its own number
Wrong:seventy-five = 705
Seventy-five is 7 tens and 5 ones: 75.
Writing digits instead of their values in expanded form
Wrong:75 = 7 + 5
The 7 means 7 tens, so 75 = 70 + 5.
Helpful Math Tip
Point to numbers you see around you (prices, page numbers, house numbers) and ask your child to read them and say how many tens and ones.
