Halves and Doubles and Near Doubles (41cm x 43cm). A set of 3 hearts.
One heart displays 1 to 6 on the left side and 2 to 12 on the right. Children have to find the match for either the double of 1 to 6 or the half of 2 to 12.
The second heart displays the numbers from 6 to 15 on the left side and their doubles from 12 to 30 on the right side.
The third heart displays the doubles in sum form for double 6, 7, 8, 9 and the near doubles for each of these (eg. 6 + 6 = ? so 6 + 5 = ?, 6 + 7= ?)
Objective: to know doubles and halves and near doubles off by heart.
