Subtraction up to 20-Exercise 1

This worksheet is designed for first graders to practice subtraction with numbers up to twenty. Students will tackle a variety of subtraction problems, helping them strengthen their understanding of how to take away and find the difference between numbers. It’s a hands-on way to build math fluency and confidence! This can be used as an independent work activity, and it's a great idea to encourage students to draw pictures or use manipulatives to visualize the problems before writing their answers. Doing so reinforces their learning and makes abstract concepts more concrete.
