Description: Help your students build place value understanding and strengthen mental math strategies with this interactive self-checking Boom Cards™ resource! This engaging digital activity is designed to help students recognize when they need to cross a ten while adding and apply number bonds to break apart numbers and make a ten. What’s Included? This Boom Cards™ set includes two interactive activities designed to support addition within 100 and develop fluency with making a ten: ✅ Activity 1: Do I Need to Cross a Ten? Students look at an addition problem and determine whether they need to cross a ten to solve. They select YES or NO and receive immediate feedback to reinforce their understanding. A movable chip on a number line provides a visual model to support learning. ✅ Activity 2: Crossing a Ten to Solve Students decompose numbers using number bonds to make a ten and solve. They record the number bond, identifying how much is needed to reach ten and how much more to solve. Students also record the ten they crossed, reinforcing place value concepts. A number line with a draggable chip provides additional support. Why You’ll Love This Resource! ✔ Builds Place Value Understanding – Students visualize how numbers break apart and regroup, strengthening their knowledge of tens and ones. ✔ Develops Mental Math Strategies – Making a ten is a foundational skill that improves addition fluency and supports future multi-digit computation. ✔ Supports Different Learning Styles
