This is a powerpoint presentation that would well for Promethean and non-promethean board users. The powerpoint introduces decimals and demonstrates how the value of a decimal can be represented on a grid (tenths, hundredths, thousands grids). Relates to 5th grade math common core standard NBT.1 (Recognize that in a multi-digit number, a number in the one place represents 10 times as much as the place its right and 1/10 of what it represents in the place to its left). Can be used for decimal-fraction equivalence and/or percentages. Focus is decimals, but easily adapted.
For Activboard users: lesson can be made more interactive by having students/teachers shade in the grids on the promethean board. Then when you click to the next slide, the answer appears. This is a fun way for students to be involved and see if they were correct.
Non-activboard users: I originally planned to utilize the Promethean board, but my pen was not working on the day of the lesson. The lesson was still great without the extra technology. Still very great visuals for students to understand decimals.
