Number Patterns and Skip Counting

Active learning helps students see skip counting as more than memorization. When children move, talk, and create patterns themselves, they connect abstract rules to concrete experiences. These hands-on activities turn silent number grids into shared explorations of how numbers grow and repeat.

• 30 min · Small Groups

Chart Highlighting: Pattern Hunt

Give each small group a hundreds chart and colored markers. Direct them to highlight skip counting in 2s across rows, 5s down columns, and 10s in vertical lines up to 1000. Groups extend one pattern beyond the chart and share the rule with the class.

What rule connects the numbers in a skip-counting pattern?

Facilitation Tip

During Chart Highlighting, ask guiding questions like, 'What do you notice about the numbers you shaded?' to keep focus on the pattern rule.

What to look for

Write three incomplete skip-counting sequences on the board (e.g., 5, 10, __, 20; 90, 80, __, 60; 3, 6, 9, __). Ask students to write the missing number for each sequence on a small whiteboard and hold it up.

Relay Race: Sequence Builders

Form teams of four. Call a start number and skip count, like 7 by 3s. First student writes the next number on a board, tags the next teammate to continue. First team reaching 100 or more wins and states the rule.

How does skip counting connect to multiplication?

Facilitation Tip

In Relay Race, set a clear 30-second limit per student to maintain energy and urgency.

What to look for

Give each student a slip of paper. Ask them to write a number pattern that starts at 20 and increases by 4, continuing it for at least five numbers. Then, ask them to write the rule they used.

Pair Chains: Create Your Pattern

Pairs get number cards from 1 to 100. They chain cards by skip counting in 4s or choose their step, then photograph or draw the sequence. Pairs present, classmates guess the rule.

How can we use a number chart to identify and predict patterns?

Facilitation Tip

For Pair Chains, supply blank hundreds charts so pairs can visualize and adjust their patterns as they work.

What to look for

Display a hundreds chart. Ask students: 'If I start at 5 and shade every other number going down the chart, what numbers will I shade? What is the pattern rule? How does this relate to counting by fives?'

Whole Class: Human Number Line

Line up students as numbers 0 to 100. Call a skip count like by 5s; students step forward to form the pattern. Reverse to show backward counting, discuss the rule as a group.

A few notes on teaching this unit

Teach skip counting by building on what students already know about counting by ones. Use hundreds charts to show how patterns form rows, columns, or diagonals. Avoid rushing to rules before exploration. Circulate to listen for students' own language about the patterns they see. Research shows that when children describe patterns in their own words first, they internalize the connections more deeply.

Students will confidently identify and extend skip-counting patterns both forward and backward. They will explain the rule they use and create new patterns while supporting peers. Class discussions will show growing flexibility in how they describe number sequences.

Watch Out for These Misconceptions

• During Relay Race: Sequence Builders, watch for students who only move forward from the starting number.

  Pause the relay and ask, 'What would happen if we started at 60 and moved backward by 5s?' Have students use the number line on the floor to walk both directions and discuss how the pattern continues.

• During Chart Highlighting: Pattern Hunt, watch for students who assume a pattern has only one possible rule.

  Bring the class together to examine one shaded section. Ask, 'Can anyone see a different rule that could fit these numbers?' Let students debate and test their ideas by shading a new section on the same chart.

• During Pair Chains: Create Your Pattern, watch for students who do not connect skip counting to multiplication.

  Hand each pair counters and a small grid. Instruct them to skip count by 4s while laying out rows of 4 counters. Ask, 'How many counters are in three rows? What multiplication sentence matches this?'
