📚 Topic Summary
Counters and blocks are amazing tools to help us understand and solve math problems. Imagine you have a basket of apples (counters) or a tower of LEGO bricks (blocks). We can use these to count, add, subtract, and even compare numbers! Using counters and blocks makes math easier to see and understand. They turn abstract numbers into something real and touchable! By moving them around, we can visualize the math problem and find the answer.
