Exact trig values of 0/30/45/60/90

This is a way to remember the exact trig values needed for higher GCSE using your left hand. There is a sheet to hand out that can be stuck in pupils’ exercise books as a reminder and a powerpoint explaining the method. It’s taken me a long time to write this so just trying to get some money for the time I put in. Thanks

Subtraction - exchanging

This uses £1 (100’s), 10pences (10’s) and pennies (units) to show what is being done when exchanging. I called it subtraction by borrowing as that’s what most teachers and pupils say. I prefer exchanging, as this is what is actually being done. Borrowing comes from the other method taught in the past, where the borrowed one is paid back.

Shows how we can use our knowledge of tables facts to 10x10 and products of multiples of 10 to divide by a single digit with an answer greater than 10.

This is a visual representation showing how short division works using £1’s, 10p’s and 1p’s. It clearly shows why the remainder becomes 10 of next place value. It’s similar to my subtraction power point which has been very popular. https://www.tes.com/teaching-resource/subtraction-exchanging-6218062
