Patterns That Get Smaller

Grade 5 Ontario Math πŸ“š β€’ Algebra

Hello my wonderful Grade 5 superstar! πŸ‘‹

I'm Kashef and today we're exploring Shrinking Patterns! These are patterns that get smaller by following a rule (usually subtracting the same number each time). They are the opposite of growing patterns. Ready to shrink some patterns? Let’s go! πŸš€

🧠 What is a Shrinking Pattern?

A shrinking pattern decreases by the same amount each time. We call this the "rule".

20, 17, 14, 11, 8, __

Rule: Subtract 3 each time β†’ Next is 5

✍️ Examples of Shrinking Patterns

Number Pattern: 50, 45, 40, 35, __

30 (subtract 5)

Shape Pattern: β˜…β˜…β˜…β˜…β˜… β˜…β˜…β˜…β˜… β˜…β˜…β˜… β˜…β˜… __

β˜… (one less star each time)

🎯 Let’s Continue the Shrinking Patterns!

1. 100, 93, 86, 79, __

72 (subtract 7)

2. 25, 21, 17, 13, __

9

3. Challenge: 80, 72, 64, 56, __

48 (subtract 8)

πŸ›’ Real-Life Shrinking Patterns

Problem 1: A candle is 30 cm tall. It burns 4 cm every hour. How tall will it be after 5 hours?

30 - (4 Γ— 5) = 10 cm

Problem 2: You have 100 points in a game. You lose 7 points every round. How many points after 6 rounds?

100 - (7 Γ— 6) = 58 points

You are a Shrinking Patterns Champion! πŸŽ‰πŸ₯³

Kashef is super proud of you! You can now spot, continue, and use shrinking patterns in math and real life.

Shrinking patterns help us understand how things get smaller over time β€” like candles burning or points decreasing in a game!
