Assessment resource Thinking addition: 2-digit plus 1-digit: assessment

TLF ID L9927

Test your ability to turn a word problem into a 2-digit plus 1-digit equation. Solve the equation without a calculator. For example, use a partitioning tool to help solve the sum 15+8. Choose which strategy you used to solve the problem. View and print a report of your results. This assessment object is the first in a series of two objects that progressively increase in difficulty.
