Hard-1 stretches first graders with comparison and two-step problems within 20. Two Show Your Work problems give a labeled box for Ava's beads and Ben's crayons so kids can track each step. Two more problems are solved without a work box, including a how-many-more comparison about Zoe and Kim's grapes.
A four-item Think About It section connects fact families and reinforces 17 minus 9.
