Using a Number Line – Negative and Positive Integer Operations

When students enter your maths class, they may have a general understanding of positive and negative numbers, but then again…they may not. They may have experience with these numbers in relation to temperature, scores in golf, or elevations. A maths vocabulary term they may not know is “integer.” They may also lack the background knowledge that integers can be added and subtracted like whole numbers. That’s where we come in!

Teach Starter has created a set of 24 task cards that your students can use to explore the concept of addition and subtraction of integers on a number line.

Through this activity, students will add and subtract integers on a number line, write equations shown by diagrams of number lines, and identify the locations of sums and differences on a number line.

Differentiate Your Positive and Negative Number Line Lessons

A team of dedicated, experienced educators created this resource to support your maths lessons.

In addition to individual student work time, use this set of task cards to enhance learning through guided maths groups, whole class lessons, or remote learning assignments. 

If you have a mixture of above and below-level learners, check out these suggestions for keeping students on track with the concepts: 

🆘 Support Struggling Students

For students who need additional support, complete these activities in small groups. Students can also use counters or drawings to show the movement of the number in either direction.

➕ Challenge Fast Finishers

If students need an additional challenge, encourage them to solve different problems that would result in a positive or negative number.

🛴 Scoot Activity 

Place the cards around the room in numerical order and give each student a recording sheet. Assign students or pairs to a starting point card. Give students time to review the card and record their answers in the corresponding space on their paper. Students will rotate to the next card when you say, “SCOOT!” Continue in this manner until students return to their starting point. 

👋 Exit Ticket 

Use these cards as a formative assessment after your lesson. Pick a random assortment of cards and project them on the board for the whole class to see. Students can record their answers on paper, sticky notes, or notebook. 

Easily Prepare This Positive and Negative Number Activity for Your Students
