Switch It!
Write the addends in different order, then solve.
4+5=
5+4=9
There are 4 white trucks and 5 gray trucks how many trucks in all?
make a double + 1 to help you add
4+5 is the same as ____+____+_____
*hint* remember, take 1 from the bigger addend, what number does it turn into, then plug in the other addend you haven't used.
4+4+1=9
so 4+5=9
***+***=******
3+3=6

Write the addends in different order, then solve.
11+7=
7+11=18
there are 3 grey cubes 6 white cubes and 2 black cubes. write the addition sentence with the sum.
__+__+__+=__
3+6+2=11
what is the doubles plus one fact for
5+6=
5+5+1=11
the addition sentence is 3+6+1=
do the problems below show grouping of the addends to make it into 2 addends?
9+1=
7+3=
True
the first problem 9+1 grouped the 3+6 to make the 9.
the second problem 7+3 grouped 6+1 to make the 7.
then turn it into a 10 fact problem
first picture should be a 10 frame with 9 circles in it then 2 circles on the bottom of the 10 frame. To switch it into a 10 fact, the picture should be one of the 2 circles outside moved into the blank space of the 10 frame. Now there is a full 10 frame and one circle outside. The new 10 fact problem is 10+1
