10640 : 2-Digit Plus 1-Digit Addition with Number Lines | Grade 1-2 Math

This 10-page set teaches Grade 1-2 students to add 2-digit and 1-digit numbers using a number line, opening with a fully worked example (12 + 6: starting at 12, hopping 6 spaces to land on 18) before six independent problems per page.

Each problem gives a 2-digit-plus-1-digit sum (for example 19 + 3, 63 + 7, 85 + 9) with blank space for students to draw their own number line and hops to find the answer, reinforcing addition as counting on rather than a memorized algorithm. 60 problems in total across the ten pages.

What's Included:

• 10-page printable PDF
• A worked number-line example at the top of every page
• 60 addition problems (6 per page) with space to draw a number line
