Problem Solving

Today (the 8th/9th) we were trying to solve leapfrog, it was so much fun doing it! We eventually worked out that 2x2 = 8 moves, 3x3 = 15 moves, 4x4 = 24 moves, 5x5 = 35 moves, 6x6 = 48 moves and 10 x10 = 120 moves (which was the whole class!)

Then we looked for patterns and recorded them (like the picture above.) 3 x 3 was very hard for some people. (The picture is 2 x 2)
