What Is the Double Rod Bead Rack Used For?
Two rods, one above the other, make doubling something a child can see. Pushing 6 beads across on the top rod and 6 on the bottom shows two white fives plus one red bead on each rod, so the total of 12 can be read without counting. For a near double such as 6 and 7, the child builds the double first and notices the single extra bead.
Halving works in reverse: show 10 or 12 beads and share them equally between the rods. For sums up to 20, fill the top rod to 10 and carry the rest onto the lower rod, so a calculation such as 9 and 4 becomes 10 and 3. The rubber clip keeps the beads in use apart from the rest, and number combinations of 10 can be practised on one rod while the other holds a second example.
What to Specify When Ordering
- Number of racks required (the description does not state how many children share one).
- Whether single-rod student racks are wanted as well.
