This medium sheet stretches first graders into number-line sums that cross ten with no tracing warm-up. Part A has nine fill-in-the-blank equations including 6 + 7, 8 + 9, 5 + 8, 9 + 5, and 7 + 9, asking kids to count on from the bigger addend and write each total. Part B is a four-pair matching activity that pairs expressions like 9 + 8, 6 + 6, 7 + 4, and 8 + 7 with answers 11, 12, 15, and 17. Together the parts push children to move flexibly between equation form and matching, a key step toward fluency within 20.
