Description
Build strong number sense with this engaging “1 Less” Boom Cards™ deck designed for preschool and kindergarten learners! Students use interactive bug manipulatives to explore the concept of “one less” in a hands-on, meaningful way. How It Works (Step-by-Step Learning) Each card guides students through a clear, scaffolded process: Match the Quantity Students begin by dragging bugs to match the given number, building one-to-one correspondence. Take One Away Students remove (drag away) one bug from the group. Find 1 Less Students count how many bugs are left and identify or type the new number. This step-by-step approach helps students see and understand what “1 less” means instead of just memorizing it.
