Find the Missing Numbers on a Number Line

Use this resource in your maths rotations, as a small group activity, or as a whole class exercise (see below) to practise identifying four-digit whole numbers and their intervals on a number line.

This set of task cards provides students with multiple types of questions that focus on the following – 

• Identifying missing numbers on a number line with varying intervals
• Identifying the interval being used on a number line
• Determining the best interval to use to build a number line with specific numbers
• Following multi-step directions to create a number line including specific characteristics.

Provide each student with a recording sheet (included) and the task cards to review. Students will identify missing numbers marked as A and B and fill in the corresponding answers for each card on their recording sheet. 

Task cards can be used with mini whiteboards, maths notebooks, smartboards, etc. 

Differentiating Your Year 4 Number Line Activities

Challenge students who already understand the concept to write the numbers that come before the numbers shown on the task card. They can also create their own task cards and swap with a partner. 

Support students who need help understanding the concepts by limiting the number of blanks on the number line. Students can refer to a place value, number chart,  or another visual aid. 

Use this resource as independent practise for fast finishers and full-class learning opportunities like warm-ups, scoot activities, lesson reviews, comprehension assessments, and more.

🛴 Scoot Activity

Place the task cards around the room in numerical order and give each student a recording sheet. Assign each student a number to start. Give students appropriate time to review the card and solve for A, B, and C, then say, “SCOOT.” At this time, the students will rotate to the next card. Continue this manner until students have made it through all the cards. 

🧑‍🏫 Group Lesson 

Present the task cards using your smartboard or another projection device and work through each together as a whole class. Students can write the answers on their recording sheet or a piece of paper. 

⌛ Exit Activity

After your lesson, pass out cards to students as a math problem they will answer on their own. Provide them with a sticky note so that they can turn in their answer as a formative assessment, making sure to write their name on the sticky note.

Easily Prepare This Resource for Your Students

Print on cardstock for added durability and longevity. Place all pieces in a folder or large envelope for easy access. 

Keep the task cards out of pockets or under desks: cut out the cards and punch a hole in each corner to place them on a binder ring. 

To turn this teaching resource into a sustainable activity, print a few recording sheets on cardstock and slip them into dry-erase sleeves. Students can record their answers with a dry-erase marker and then erase and reuse them.

Because this activity includes an answer sheet, we recommend printing one copy of the entire file first. Then, make photocopies of the blank worksheet for students to complete.
