A great way to digitally 'flash' the place value of 2 and 3 digit numbers using a projector or interactive whiteboard. Students identify the place value of each amount using the base ten blocks displayed on each slide. Answers are also given when played in slide show mode.
My kiddies really enjoy using their whiteboards or place value houses to record their answers.
This resources can also be printed to use in maths groups or handheld flash cards.
