Application practice: first graders decide which two addends make 10 first in problems like 2+8+3 and 6+4+5. Four multiple-choice questions test whether children can spot the 10-partners quickly. Five real-world fill-in word problems about marbles, pages, crayons, points, and cookies then connect the make-ten strategy to everyday adding situations, helping Grade 1 kids see the math alive in their daily playground and classroom activities.
