1. Gaining Practice

1.1. Here is a website you can go on for more parcatice there are tuns of games on adding and subtraction.

1.2. Here is another website you can go on for more parcatice there are more fun games on addition and subtraction.

2. =52 crayons left in the box

12. Students develop strategies for adding and subtracting whole numbers based on their prior work with smaller numbers. They use a variety of models, including discrete objects and length-based models (e.g., cubes connected to form lengths), to model add-to, take from, put together, take-part, and compare situation to develop meaning for the operations of addition and subtraction, and to develop strategies to solve arithmetic problems with these operations. Students understand connections between counting and addition and subtraction (e.g., adding two is the same as counting on two). they use properties of addition of addition to add whole numbers and to create and use increasingly sophisticated strategies, children build their understanding of the relationship between addition and subtraction .
