Join two small groups
Count two visible groups, join them and find how many there are altogether. Twelve varied examples across three practice pages, with separate answers.
Each rod is made of equal squares: the rod labeled 4 has four squares and is twice as long as the rod labeled 2. Print at actual size to keep all the units equal. The page is useful as a counting reference or as large, adult-prepared pieces for comparing lengths.
Connect the numerals 1–10 with equal units and compare how many squares each rod contains.
Use only the rods for 1, 2 and 3.

An adult supervises cutting. These are original equal-unit paper rods, not a claim of alignment with a commercial manipulative system.
