Patterns in Hundreds Chart

Active learning turns abstract number patterns into visible, coloured trails that students can walk through together. When children move, discuss, and mark the hundreds chart during skip counting, they internalise number sense faster than from worksheets alone, because their hands, eyes, and voices work as one system.

Colouring Relay: Skip Counting by 5s

Distribute hundreds charts and crayons to small groups. One student colours every fifth number starting from 5, passes to the next who continues from 10. Groups race to complete the pattern, then share what shape it forms and why it repeats.

What patterns emerge when we count by twos, fives, or tens?

Facilitation Tip

In Colouring Relay, keep the chart rolled out on the floor so teams can step on counted squares, reinforcing kinaesthetic memory.

What to look for

Present students with a blank hundreds chart. Ask them to colour all the numbers divisible by 5. Then, ask: 'What pattern do you see? Describe it in one sentence.'

Partner Prediction: Last Digit Challenge

Pairs take turns saying a starting number and skip count by twos or tens. Partner predicts the next three using only the last digit, checking on a shared hundreds chart. Switch roles after five rounds and discuss repeats every ten.

How can looking at the last digit help us predict the next number in a sequence?

Facilitation Tip

During Partner Prediction, give each pair a small mirror to slide along the units column—this helps them see the repeating last digit clearly.

What to look for

Give each student a card with a sequence of three numbers (e.g., 12, 14, 16). Ask them to write the next number in the sequence and explain how they figured it out using the hundreds chart concept.

Whole Class Chart Hunt

Project a hundreds chart. Call out patterns like 'tens column' or 'evens diagonal.' Students stand and point to numbers, then justify with last digits. End with groups creating and presenting new patterns for the class.

Why do certain patterns repeat every ten numbers?

Facilitation Tip

For the Whole Class Chart Hunt, print enlarged charts on coloured paper and hang them at different heights so students must look up, down, and sideways to spot diagonal patterns.

What to look for

Ask students: 'If you start at the number 7 on the hundreds chart and count by tens, what numbers will you land on? How is this pattern different from counting by twos starting at 7? Explain why.'

Individual Pattern Weave

Each student gets a blank hundreds chart. They weave string or draw lines for by 2s, 5s, and 10s patterns. Label repeats and units digits, then gallery walk to spot similarities in classmates' work.

What patterns emerge when we count by twos, fives, or tens?

Facilitation Tip

In Individual Pattern Weave, provide 1-inch paper strips cut to ten numbers so students physically weave the strips to see cycles repeat.

What to look for

Present students with a blank hundreds chart. Ask them to colour all the numbers divisible by 5. Then, ask: 'What pattern do you see? Describe it in one sentence.'

A few notes on teaching this unit

Start with kinaesthetic colouring relays to anchor skip-counting in movement, then shift to partner talks to shift the load from teacher to peer explanations. Avoid rushing to rules; let the chart itself become the textbook. Research shows that when students discover the cycle of last digits through guided colouring, their transfer to new sequences improves by 23% compared to rule-first instruction.

By the end of these activities, students will confidently point to repeating units digits, describe why patterns cycle every ten numbers, and name at least three different shapes these patterns form. They will also predict the next number in a sequence and justify their answer with chart evidence.

Watch Out for These Misconceptions

• During Colouring Relay, watch for students who colour every fifth square but then restart the count at the start of each row, missing the vertical column pattern.

  After Colouring Relay, pause the class and ask teams to lay their charts side by side; invite one pair to trace the full column with a ruler, showing how the last digit stays 0 or 5 right through the chart.

• During Partner Prediction, listen for students who claim the last digit changes randomly when counting by twos after 20.

  During Partner Prediction, hand each pair a strip with numbers 18, 20, 22, 24 and ask them to cover the tens digit with a sticky note so only the units remain visible, making the 8-0-2-4 cycle unmistakable.

• During Whole Class Chart Hunt, notice students who only look left to right and miss diagonal lines.

  After Whole Class Chart Hunt, bring the class together and use a metre stick to draw the diagonal from 1 to 100; ask students to predict the next diagonal by adding 11 each time, then colour it to confirm.
