My child worked on addition and subtraction through 20

Math

• The child has learned to add and subtract numbers up to 20.
• They have practiced using different strategies such as counting on, using a number line, and using manipulatives to solve addition and subtraction problems.
• The child has gained an understanding of the relationship between addition and subtraction, recognizing that they are inverse operations.
• They have also developed their mental math skills by solving simple addition and subtraction problems mentally.

For continued development, encourage the child to practice addition and subtraction in real-life situations. For example, they can help with grocery shopping by adding up the prices of items or subtracting discounts. They can also play games that involve mental math, such as "Math War" or "Around the World". Additionally, providing opportunities for the child to explain their thinking and solve word problems related to addition and subtraction will help reinforce their understanding of the concepts.
