Question

Draw or write to explain why 1 hundred 4 tens and 14 tens name the same amount.

Answer 1

14*10= 140 (14 tens)
100+10+10+10+10=140. (1 hundred 4 tens)

Answer 2

1 hundreds = 100

4 tens = 4 x 10 = 40

100 + 40 =  140

------------------------------------------------------------------------------------------------------------------

14 tens = 14 x 10 = 140

------------------------------------------------------------------------------------------------------------------

As shown above, when you combine the groups within the different groups, the groups essentially have the same amount, 140.

hope this helps
