Groups of Ten (from Chapter 12 Elementary and Middle School Mathematics by John A. Van De Walle; Pearson Education, Boston 2004)
of counters of different types. Bags may have toothpicks, buttons, beans,
plastic chips, connecting cubes, craft sticks, or other items. Children have a
record sheet similar to the ones below. The bags can be placed in stations
around the room or each pair of children can be given one. Children dump
out and count the contents.
The amount is recorded as a number word. Then the counters are grouped in as many tens as possible. The groupings are recorded on one of the forms below. Bags are traded, or the children move to another station after returning all the counters to the bag.
