A visual discussion starter for you:
These three pots of sandwich filling cost £1 each. The flavours are egg mayo, chicken & bacon and cheese & onion.
How much would the 182g chicken filling cost if it weighed the same as the others?
The large pots contain 5 servings and the small pot contains 3 servings – are they the same size serving?
If you zoom in on the picture you could generate your own questions based on the nutritional information eg calories per serving.
You could extend this to the snacks in students’ bags. Are they as healthy as they think?
Simple little starter for you today. Minimum preparation, personalised challenge.
- 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?
- 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!
