Math Worksheet with Reptiles and Amphibians: Add and Subtract with Symbols

This math worksheet asks the child to read a key, substitute the values, and evaluate each expression with Reptiles and Amphibians. First the child studies the key, where every picture stands for a small number. Then they tackle the expressions, each one a string of symbols linked by plus and minus signs. The child replaces each Reptiles and Amphibians with its value, then adds and subtracts in order until one answer is left, sometimes as high as forty. Handling several symbols and two operations in the same sentence is exactly the kind of calculating Grade 2 calls for, and the picture key gives the child a friendly way in. You can sit alongside and read the key together, then watch your child solve each problem step by step — substituting, adding, subtracting, and arriving at a clear, correct total.

In this variant the key is clear and the first expressions are simple, a calm way to warm up. The child looks up what each Reptiles and Amphibians is worth, substitutes the values, and solves a short add-and-subtract sentence. Early success here makes the child ready to take on the longer expressions, with no rush and no score along the way.
