A thermometer is a useful tool when it's hot or cold outside. Did you know it's also a useful tool for solving word problems? Your child can count forward and backward on the thermometer to add and subtract degrees. It's a great lesson on solving step by step, and it helps remind him that number lines are a great way to visualize solutions to maths problems.
