Rafael broke up a large array for 6 × 3 into two new arrays. Both of his new arrays are the same size. What were the size of the two arrays?
Rafael made two arrays of 2x3.
Rafael made two arrays of 3x3.
Rafael made two arrays of 9x9.
Rafael made two arrays of 6x6.
Which equation shows matches how the Distributive Property is used in the picture to find 4x8?
4 × 8 = (3 × 8) + (1 × 8)
4 × 8 = (2 × 4) + (2 × 4)
4 × 8 = (4 × 4) + (4 × 4)
4 × 8 = (2 × 8) + (2 × 8)
Besides using a 2s fact and doubling it, what is another way to break apart 4x7 using facts you already know?
Use 2 × 7 = 14 and 2 × 7 = 14; 14 + 14 = 28
Use 1 × 7 = 7 and 3 × 7 = 21; 7 + 21 = 28
Use 7 × 7 = 49 and 4 × 4 = 16; 49 + 16 = 65
Use 4 × 1 = 4 and 4 × 2 = 8; 4 + 8 = 12
Selena arranged 3 rows of plants in her garden. She put 9 plants in each row. Which equation shows how to break apart 3x9 using facts you already know?
Use 1 × 9 = 10 and 2 × 9 = 11; 10 + 11 = 21
Use 2 × 9 = 18 and 2 × 9 = 18; 18 + 18 = 36
Use 1 × 9 = 9 and 2 × 9 = 18; 9 + 18 = 27
Use 9 × 9 = 81 and 3 × 3 = 9; 81 + 9 = 90

The graduating students are standing in 7 equal rows. There are 9 students in each row. How would you use 5s and 2s facts to solve how many students are graduating?
Use 5×9=45 and 2×9=18; 45+18=63
Use 5×7=35 and 2×7=14; 35+14=49
Use 5x9=45 + 2×9=28; 45+28 = 73
Use 5×9=45 and 2×8=16; 45+16=61
Chrissy bakes 3 cherry pies. She cuts each pie into 6 slices. What two known facts can 3x6 be broken into to find the number of slices of cherry pie?
1 × 6 = 6 and 2 x 3 = 6
1 × 6 = 6 and 2 × 6 = 12
2 × 6 = 12 and 2 × 6 = 12
1 x 6 = 6 and 1 x 6 = 6
7x7=
6x5=
Which known facts can help you find the answer to 8 × 5? Choose all that apply.
5 x 5 = 25 and 5 x 5 = 25
3 × 5 = 15 and 5 × 5 =25
4 × 5 = 20 and 4 × 5 = 20
2 x 5 = 10 and 6 x 5 = 30
8x4=
