Explain how you can use base ten blocks to find [tex]1.54 + 2.37[/tex].

0.00
*First column to your left - ones column (1) *Column just after decimal place, in the middle - tenths column (1/10) *Column to the far right - hundredths column (1/100)
The only numbers that can go in these columns are 0-9.

1.54 + 2.37
= (1 + 5/10 + 4/100) + (2 + 3/10 + 7/100)
= 1 + 5/10 + 4/100 + 2 + 3/10 + 7/100
= 3 + 8/10 + 11/100
= 3 + 8/10 + (10/100 + 1/100)
= 3 + 8/10 + (1/10 + 1/100)
= 3 + 8/10 + 1/10 + 1/100
= 3 + 9/10 + 1/100
= 3.91
