Numbertalks  – using addition strategies for doubles/ near doubles.

Example:  Which doubles/near-double strategies will you use to solve the following problem:  8+9   

a. 8+8 +1  (using this double decomposes 9 into 8+1)

b. 9+9-1    ( add an extra 1 and then subtract it from the total)

c. 10+10 -3  ( 8+2=10 , 9+1=10,  10+10= 20 –3 = 17 using this double requires the student to add 3 extra and then subtract the extra 3 from the total)

Doubles using basic facts up to 10

3+3,  3+4,  3+2
