• They have practiced problem-solving skills by using addition and subtraction to analyze data and make predictions.
• They have learned about the properties of addition and subtraction, including commutative, associative, and identity properties.

Continued development can be supported by incorporating hands-on activities that involve addition and subtraction, such as using manipulatives or playing math games. Encourage the child to solve word problems that require addition and subtraction skills to develop their problem-solving abilities. Additionally, providing opportunities for real-world applications of addition and subtraction, such as cooking or budgeting, can help reinforce their understanding of these concepts.
