Core Skills Analysis
Math
Lily completed Chapter 11 of the Dimensions Math workbook, where she practiced comparing numbers by using subtraction as a tool. She created comparison subtraction stories, turning everyday situations into math problems, and she built picture graphs to display the results. Through these activities, Lily reinforced her ability to determine which of two numbers is larger or smaller and to represent data visually. She also reviewed subtraction facts, applying them in real‑life contexts.
Tips
To deepen Lily’s understanding, encourage her to collect real objects (like snacks or toys) and compare quantities using subtraction, then record the results in a picture graph. Introduce a “comparison journal” where she writes a short story each day that includes a subtraction comparison, fostering both math and language skills. Set up a game of “Number Detectives” where Lily finds pairs of numbers in the house and determines the difference, reinforcing mental subtraction. Finally, incorporate technology by using simple tablet apps that let her build interactive bar graphs from her data.
