Ten Groups - Add, With Carry, Less than 20

This topic focuses on addition problems involving integers, requiring calculations with carrying, all within the number range of less than 20. It is part of a broader unit on adding and subtracting one- and two-digit integers. Students engage with various questions that involve visual aids (like triangles and circles of different colors) to solve addition problems, and each problem presents several answer options. The skill of adding with carrying is crucial to solve these exercises effectively.
