Count On: Counting in 4s, 8s, 50s and 100s

About This Resource

A free Grade 3 math worksheet on counting forward and backward in steps of 4, 8, 50 and 100. Students complete number sequences, find the missing number, spot patterns in the ones digits, connect counting in 4s and 8s with doubling and solve short real-life counting problems. Includes a timed lesson plan, a six-activity worksheet, an editable Word version and answer key.

Overview

Counting in steps builds fluency for multiplication and for working with larger numbers. Students count in 4s and 8s from zero and from other starting numbers, notice that every number in the 4s and 8s sequences is even, and see that counting in 8s jumps over every other number in the 4s sequence, because 8 is double 4. They count in 50s and 100s to 1,000 and see which digits change. Students fill in sequences, find missing numbers, sort numbers and use counting to solve problems about animal legs and arms.

Grade 3 math (ages 8–9) 40 minutes Counting number patterns multiplication facts reasoning

Student Task

Count aloud together in 4s with claps on every number, then in 8s.
Model the patterns on a number line, then do activities 1 and 2 together.
Students complete activities 3 to 6. Answers are in the answer key.

Classroom Use

Clap and count: students clap on every 4th number while counting to 40.
Number line jumps: students draw jumps of 50 from 0 to 500.
Fizz count: the class counts around the room and says buzz on every multiple of 8.

Differentiation

Support: give a hundred chart and focus on 4s and 100s. Challenge: students count in 4s and 8s from numbers that are not multiples (3, 7, 11…) and in 50s backward from 1,000.

Answer Key & Assessment

Activities 1 to 5 check counting and patterns (answer key included). Activity 6 shows whether students can apply counting to a problem.

Learning Objectives

Count forward and backward in 4s, 8s, 50s and 100s.
Find missing numbers in counting sequences.
Explain patterns, such as the link between counting in 4s and 8s.

Teacher Tips

Encourage students to use known facts: counting in 8s is like counting in 4s and taking every second number. When counting in 50s, the numbers end in 50 or 00, which helps students check their answers.
