This is a lesson that I have thought about putting together for a long time, but as I don't tend to teach a lot of KS3 or younger anymore then it has been a long time doing. 19 slides.
Place value is such a vital skill and cornerstone in Mathematics and it never ceases to amaze me how many pupils struggle with it as a concept even at KS4. This lesson combines lots of different activities and types of questions to help pupils improve their understanding of number and place value. It includes a link to a video and a look at Abacuses, which are extremely popular for mental mathematics in China, India and South East Asia.
The worksheet is linked to Abacuses mainly as a way of improving understanding of place value and I have added some additional help sheets and handouts for supporting the less able pupils in the class. I often laminated these so pupils can use MWB pens to write directly on them and thus they are also bigger in size. This PPT has 19 slides, so plenty of material... oh plus importantly excellent teaching slides, learning objectives, keywords, starter, plenary and ANSWERS.
