A math double is the process of adding a number to itself. A math double is a simple addition process that many children learn in the first grade. Teaching these doubles to children helps them perform more quickly in math and prepares them for harder math in the future. Learning doubles is largely a matter of memorising the answers, and many methods are available. Using a multi-step approach is the best way to ensure that a child, regardless of learning style, learn the best procedure to answer easily any doubles problem.

For each verse, have that number of children link arms. For the first verse have one child walk on one side of the line and one other child walk on the other side. For each verse, add children until you get to 10 or until you run out of children. Have the children count how many total children are used for each verse.
