Students match numbers to their visual representations by snapping together jigsaw puzzle pieces in this number sense activity. Each card pairs a number, and optionally its word form, with a counter image such as cookies, dots, ten frames, hands, or balloons; learners drag and connect the pieces that belong together, with correct matches locking into place. This activity supports TEKS K.3.C (compose and decompose numbers to 10).
Skills: number recognition, one-to-one correspondence, ten-frame fluency, visual matching. Kindergarten-2nd grade.
