Math

• The child has learned how to add and subtract integers using horizontal and vertical number lines.
• They have gained a visual understanding of integer addition and subtraction by graphing integers on number lines.
• The activity has helped the child understand the rules and patterns related to adding and subtracting integers.
• Through graphing integers, the child has developed the ability to visually represent and conceptualize mathematical operations.

For continued development, encourage the child to create their own integer addition and subtraction problems and solve them using horizontal and vertical number lines. They can also explore real-life situations where integers are used and apply their understanding of addition and subtraction to solve problems in those contexts. Additionally, they can practice making connections between the graphical representations and symbolic notation of integers.
