Ideally print on card stock and laminate. Cut along lines (this is something children can do!). There is every you need to complete a short (square) chain or a long (cubing) chain. Lay five 7 bars together, count and label for a short chain (1 square goes at the end). Lay all 7 bars together for a long chain, with a square laying on top of every 7th bead bar, with a square and at the cube at the end. Label with correct label the last bead of every bar.
