Number bond challenge

Number bond Challenge!. Each child in the group was given an envelope with 9 triangles. Each triangle had 3 numbers on it. The children then had to make one large triangle from the smaller triangles. The challenge was to match each side of the triangle with another triangle to ensure the numbers totalled 10.  After a minute or two, the children were given a clue...the colours also had to match. Sydney was the first to solve the challenge within 10 minutes!!!
