One of the most difficult things for many kids to grasp in math are word problems! Students need to actually think about the problem and how to solve it. I have students independently complete a word problem every day as practice (I will read the problem out loud) and then we check the work together, with students correcting as needed. So there is no pressure to not take a risk to solve the problem! I think this really helps students learn HOW to solve the problem-not just a formula!
This product on TpT has 60 word problems of varying types (addition, subtraction, missing addend, and comparison) and difficulty (some within 10, some within 20) to help you teach word problems to your first grade students!
