Math Worksheet with Ocean Life: Add and Subtract with Symbols

What is each picture worth? On this math worksheet, the child answers that with the key, then uses those values to solve. Every Ocean Life is set equal to a single-digit number at the top, and below, expressions of three or four symbols wait to be worked out. The child substitutes the right number for each picture, then evaluates the adding and subtracting from left to right, building toward a total that can reach about forty. This is Grade 2 arithmetic in a playful coat: real two-step calculation dressed up with familiar Ocean Life. There is no timer and no score, just careful substitution and steady solving. Each finished expression shows the child that they can move from picture to number to answer all on their own, which is a satisfying kind of confidence to grow.

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 Ocean Life 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.
