Dinosaur maths quest: multiplication

A story-led junior maths adventure using fossils, footprints and giant timelines to use equal groups, arrays and repeated patterns.

Quick answer

By the end of this Dinosaur maths quest, you'll know how to use equal groups, arrays, and repeated addition to solve multiplication problems – just like a palaeontologist discovering how many footprints are in a dinosaur trackway!

Learning outcome

By the end of this Dinosaur maths quest, you will be able to:
  • Use equal groups to solve multiplication problems
  • Recognise arrays in real life
  • Use repeated addition to understand multiplication
  • Apply multiplication to solve problems about dinosaurs and their footprints
Success signs:
  • You can draw an array to show 4 x 3
  • You can count equal groups to find the total
  • You can solve a problem like "5 groups of 6 footprints" using repeated addition
  • You can explain how multiplication helps you find totals quickly

Why this matters

Multiplication helps you count things quickly when you have equal groups. It's like being a detective – you can spot patterns and use maths to solve mysteries! When you're a palaeontologist (a scientist who studies fossils), you use multiplication to count dinosaur footprints, estimate how many eggs were in a nest, or work out how many bones are in a dinosaur skeleton. In everyday life, multiplication helps you share snacks, count your toys, or work out how much money you'll spend on your favourite things.

How it works

Multiplication is really just repeated addition. If you have 3 groups of 4 dinosaurs, you can add 4 + 4 + 4 to get 12. That's the same as 3 × 4 = 12. You can also think of it as an array – like a grid of dinosaurs. Arrays help you see multiplication clearly. If you have 3 rows of 4 dinosaurs, you have 3 × 4 = 12 dinosaurs in total.

Examples you can see

Let's imagine you're exploring a dinosaur dig site. You find 5 rows of dinosaur footprints, and each row has 6 footprints. How many footprints are there altogether? Method 1: Repeated Addition 6 + 6 + 6 + 6 + 6 = 30 footprints Method 2: Equal Groups 5 groups of 6 footprints = 5 × 6 = 30 footprints Method 3: Arrays Draw a grid with 5 rows and 6 columns. Count all the squares = 30 footprints Let's try another one: You see 4 dinosaur eggs, and each egg has 3 baby dinosaurs inside. How many baby dinosaurs are there? Method 1: Repeated Addition 3 + 3 + 3 + 3 = 12 baby dinosaurs Method 2: Equal Groups 4 groups of 3 baby dinosaurs = 4 × 3 = 12 baby dinosaurs Method 3: Arrays Draw a grid with 4 rows and 3 columns. Count all the squares = 12 baby dinosaurs

Try it as a mini adventure

Dinosaur Footprint Quest You are a young palaeontologist on a mission to count dinosaur footprints in a prehistoric trackway. Here's your quest: 1st time: You find 3 rows of footprints. Each row has 5 footprints. How many footprints do you count? 2nd time: You see 4 rows of footprints. Each row has 7 footprints. How many footprints are there? 3rd time: You spot 6 rows of footprints. Each row has 4 footprints. How many footprints do you count? 4th time: You notice 8 rows of footprints. Each row has 3 footprints. How many footprints are there? 5th time: You discover 10 rows of footprints. Each row has 2 footprints. How many footprints are there? 6th time: You find 7 rows of footprints. Each row has 6 footprints. How many footprints are there? 7th time: You see 9 rows of footprints. Each row has 5 footprints. How many footprints are there? 8th time: You count 5 rows of footprints. Each row has 8 footprints. How many footprints are there? 9th time: You see 6 rows of footprints. Each row has 9 footprints. How many footprints are there? 10th time: You discover 11 rows of footprints. Each row has 4 footprints. How many footprints are there? 11th time: You count 12 rows of footprints. Each row has 3 footprints. How many footprints are there? 12th time: You find 10 rows of footprints. Each row has 10 footprints. How many footprints are there?

Common mistakes

  • Mistake: Thinking that 3 × 4 = 12, but then adding 3 + 4 = 7 instead of 4 + 4 + 4 = 12 Why it happens: Mixing up multiplication with addition Fix: Use repeated addition to check your multiplication, or draw an array to see the groups clearly
  • Mistake: Counting rows and columns wrong when drawing arrays Why it happens: Not being careful about which is the row and which is the column Fix: Always start with the first row, then count how many columns there are in each row
  • Mistake: Forgetting that 0 × anything = 0 Why it happens: Not understanding that zero groups of anything means nothing Fix: Remember: if there are no groups, there are no items – so 0 × 5 = 0

Parent and carer guide

Help your child understand multiplication by:
  • Using everyday examples like 4 groups of 3 toys or 5 rows of 6 cookies
  • Encouraging them to draw arrays or make equal groups with objects
  • Playing multiplication games like "What's 3 × 4?" and checking with repeated addition
  • Letting them explore how multiplication helps them solve problems faster
  • Practising with 10 minutes of fun counting games, like counting dinosaur footprints or eggs
Parents, don't worry if your child makes mistakes – they're learning! The key is to keep it fun and encouraging. You can also make a quick chart of the times tables as you go, so your child sees the patterns.

Practice questions

  1. How many legs do 5 dinosaurs have if each has 4 legs?
    • Answer: 5 × 4 = 20 legs
  2. How many eggs are in 3 nests if each nest has 7 eggs?
    • Answer: 3 × 7 = 21 eggs
  3. How many scales does 6 dinosaurs have if each has 10 scales?
    • Answer: 6 × 10 = 60 scales
  4. How many teeth do 8 dinosaurs have if each has 5 teeth?
    • Answer: 8 × 5 = 40 teeth
  5. How many feathers are on 4 birds if each bird has 12 feathers?
    • Answer: 4 × 12 = 48 feathers

FAQ

What is multiplication?

Multiplication is a way to add equal groups quickly. Instead of adding 5 + 5 + 5 + 5, you can multiply 4 × 5 = 20.

Why do we need multiplication?

Multiplication helps us count things faster when we have equal groups. It's useful for sharing, cooking, shopping, and science!

How can I help my child learn multiplication?

You can use everyday examples, play games, draw arrays, and practice with repeated addition to build a strong understanding.

What's the easiest way to learn multiplication?

Start with repeated addition, then use arrays and equal groups. Practice with real objects and games to make it fun.

What if my child gets confused between multiplication and addition?

Use visual models like arrays or equal groups. Practice with repeated addition to show that multiplication is repeated addition.
