Why this matters

Planning events uses lots of maths! Whether it's a birthday party, a school play, or a sports day, event planners need to use maths to know how much money to spend, how many chairs to buy, and how long activities will take. When you're a junior event planner, you're using maths to make sure everything runs smoothly and everyone has fun.

How it works

To be a junior event planner, you need to use maths in a few important ways:
  1. Work out your budget
  2. Plan seating
  3. Count how many things you need
  4. Make a simple schedule

Examples you can see

Let's imagine you're planning a birthday party for 12 friends. Here's how you use maths to plan it: Step 1: Make a budget You have £30 to spend on party decorations and food. You buy 3 balloons for £1 each. You buy 2 cakes for £5 each. You spend £3 + £10 = £13 on balloons and cakes. You have £30 - £13 = £17 left for other things. Step 2: Plan seating You have 12 friends coming. You have 4 tables that each hold 3 people. So 4 tables × 3 people = 12 people can sit. Perfect! That's exactly how many friends you have. Step 3: Count items needed Each friend gets 2 party hats. You need 12 friends × 2 hats = 24 party hats. Each friend gets 1 drink. You need 12 drinks. Step 4: Make a schedule You plan 3 activities: - Games for 20 minutes - Cake time for 10 minutes - Present opening for 15 minutes Total time = 20 + 10 + 15 = 45 minutes

Try it as a mini adventure

You are the junior event planner for your class's end-of-year party. You have £40 to spend and 20 friends coming. Task 1: Make a budget You decide to spend: - £10 on decorations - £15 on food (pizza and drinks) - £12 on party games - £3 on party hats Check if your budget is correct: £10 + £15 + £12 + £3 = £40. That's right! Task 2: Plan seating You have 4 round tables. Each table can hold 5 people. How many people can sit at the tables? 4 tables × 5 people = 20 people. That's perfect for all your friends! Task 3: Count party items Each friend gets: - 1 party hat - 1 drink - 1 slice of pizza How many of each item do you need? - 20 party hats - 20 drinks - 20 pizza slices Task 4: Plan the schedule You plan these activities: - 10 minutes: Games - 15 minutes: Pizza - 10 minutes: Present opening - 5 minutes: Thank you speech Total time = 10 + 15 + 10 + 5 = 40 minutes

Common mistakes

  • Mistake: Adding up costs wrong
    Why it happens: When adding, children might make simple addition errors.
    Fix: Use counting on fingers or a number line to double-check your sums.
  • Mistake: Forgetting to count all guests
    Why it happens: Children might count friends twice or miss one.
    Fix: Count each friend once and write their name down to keep track.
  • Mistake: Making tables too small
    Why it happens: Children might forget to multiply the number of tables by the number of people each can hold.
    Fix: Draw a picture of your tables and write how many people each one holds.
  • Mistake: Not checking if you have enough money
    Why it happens: Children might spend too much and not have enough for everything.
    Fix: Keep a running total as you spend money and make sure it doesn't go over your budget.

Parent and carer guide

To help your child be a junior event planner, try these 5-10 minutes of fun maths:
  • Ask your child to plan a pretend party for a number of guests
  • Use a small budget, like £20 or £30
  • Have them add up costs of decorations, food, and games
  • Ask them to work out how many chairs or plates they need
  • Encourage drawing tables and seating arrangements
  • Check their maths together, but let them do the thinking
  • Ask them to explain their planning to you
Remember, it's okay if they make small mistakes – that's how we learn! Focus on the process, not just the answer.

Practice questions

  1. You have a budget of £25 for a party. You spend £8 on decorations and £12 on food. How much money do you have left?
