Core Skills Analysis
Math
Cillian practiced reading subtraction equations with numbers up to 10 and used beans as concrete objects to represent what each equation meant. By removing beans, he connected the written subtraction symbols and numbers to the action of taking away from a group. He completed two subtraction worksheets and read the equations aloud, strengthening his ability to explain mathematical thinking verbally. This activity helped Cillian build early conceptual understanding of subtraction rather than relying only on memorized answers.
Tips
Tips: Continue with hands-on subtraction using beans, buttons, or toy animals, asking Cillian to build each equation and describe what was taken away and what remained. Invite him to draw pictures for several equations and then write the matching number sentence. Create simple story problems involving snacks or toys, and have him act them out before solving. Finish with a quick “build, say, write” routine so he represents each problem with objects, explains it aloud, and records the equation.
