Checks Into Stripes

Strategies and Hints

  1. Students might suggest sliding the second and fourth rows to the left or right.

  2. The problem says you may touch only pieces 1 and 2. However, you might hold on to piece 1 and use it to push other tiles.

Solution

Move pieces 1 and 2 next to the two black tiles in the right column. Then, use them to slide the second and fourth rows to the left.
