What Is the Single Rod Bead Rack Used For?
Because the beads change colour every five, a child can show 8 as five white and three red in a single push instead of counting one bead at a time. This structure of five and ten is the key to quick mental arithmetic: to add 8 and 5, the child fills up to 10 and sees 3 more beyond it. Number combinations of 10 become visible too, as a group of 10 beads splits into 7 and 3 or 6 and 4.
Doubles such as 6 and 6, and near doubles such as 6 and 7, can be built and compared along the rod, while halving 8, 10 or 12 means splitting the beads into two equal parts. Give each child a rack, call out a sum, and ask everyone to hold up their answer with the clip marking the result, so the teacher can check the whole class at a glance.
