Math Worksheet with Dinosaurs: Add and Subtract with Symbols

Trade pictures for numbers, then solve — that is the rhythm of this math worksheet with Dinosaurs. The key at the top assigns each symbol a single-digit value, and the rest of the page is a set of add-and-subtract expressions built from those symbols. The child reads an expression, replaces each picture of Dinosaurs with the number it stands for, and then evaluates: adding where there is a plus, taking away where there is a minus, working steadily toward the total. Results can reach about forty, so the child is adding and subtracting within numbers that genuinely belong to Grade 2. This blend of a simple key and multi-term sentences is a lovely way to practise substitution and two-step calculation, with the Dinosaurs keeping the whole page warm and inviting.

This version asks the child to substitute values and solve expressions that build toward totals near forty using Dinosaurs. Looking up each picture, swapping in its number, and then adding and subtracting carefully gives the child genuine two-digit results. It is calm, confident Grade 2 practice — substitute, calculate, and write the answer, one expression at a time.
