A lesson plan describing how to use the Gattegno chart for the following mathematical aims: •multiplying whole numbers, and decimal numbers by 10, 100, … •dividing whole numbers and decimal numbers by 10, 100, … •multiplying by decimal numbers •converting fractions to decimals •index notation •looking for generalisations •developing a common language for discussion of ideas.
Very good although I think your chart is upside down! I've always seen it the other way (so multiplying goes up the chart) which to my mind reinforces the fact that multiplying by 10, 100 etc increases the value. Just what I needed for a suggested activity though! :)
