# 300. Name that Number

Simple little starter for you today. Minimum preparation, personalised challenge.

Equipment

• Paper or whiteboards

Instructions

• Hand out mini whiteboards or use paper.
• Write the alphabet on the board.
• Assign each letter a value. You can go for the standard 1 to 26 or choose a mixture of big/small numbers – maybe a negative number or two.
• Get each student to write down their name and associated numbers.
• Write a target number eg 100 on your board.
• Each student must use the numbers of their name to make the target. If they can’t, they must get as close as they can.
• If they make that target either find another way or change the target number.
• Alternatively once they’ve finished they could use their classmate’s name – did they use the same method?

Variations

• You can make this as easy or difficult as you want by changing the target or the alphabet numbers.
• Throw in some fractions or decimals – go all the way and thrown in algebraic indices or standard form. You are the best person to judge your students’ level of challenge..
• You could allow surnames, you could insist all numbers are used.
• Put three alphabet variations on the board for mixed ability teaching.
• If you are teaching a class not in the English language (eg Welsh, Greek, Russian), where the alphabet is different, this still works just assign each letter/character a number in the same way.
• The possibilities are huge – have fun!

Note: this isn’t numerology, it’s proper Maths!

# 60. Special Offer 3

You know, once you start noticing odd logic in special offers, you notice them everywhere. I’m collecting all the ones I find with the aim of creating a numeracy/ mental arithmetic/ problem solving board. I hope it will start some good discussions – especially if I throw in some good value offers too.
