I took the 2 from the 27 which is 25.

25 x 7 = 100 [He likely means 25 x 4]

Then I thought of the extra 2’s that I took away from the 27’s which became 25, so I did 4 x 2 = 8.

8 + 100 = 108

4 x 20 = 80

4 x 7 = 28

80 + 28 = 108

Use the dynamic open array below to represent Darren’s strategy.  To begin, drag the black dots left to right and top to bottom.

10 x 4 = 40, then we did that again.

40 + 40 = 80.

4 x 7 = 28

Then we added those two together, which equals 108

27 x 2 = 54

And since 2 is half of the 4 we are using in the main problem, we just did it multiplied by 2, and that is 108.

27 + 3 = 30

30 x 4 = 120

120—(3 x 4) = 108
