Vocabulary, Foldables, and Instructions for Dividing a Decimal by a Whole Number and Dividing a Whole Number by a Decimal. Updated to include a Beat the Clock game for each skill. Students answer quickly to trying to answer before the computer does.
**Updates From 53 slides to 88 slides! More practice slides added. Now featuring Beat the Clock: the students try to answer the problem before the computer does. I wanted to update the look. I changed the background and updated the fonts on some key slides. When I did this I included some slides that can now be printed as posters. I also updated the foldable.**
I used this Powerpoint in my classroom over two days.
On the first day I focused on Dividing a Decimal by a Whole Number using decimal alignment as a strategy. I also reviewed basic vocabulary needed for division including divisor, dividend, and quotient.
On the second day we dealt with the challenging concept of Dividing a Whole Number by a Decimal.
The Powerpoint goes breaks each topic into step by step instructions and allows the students to attempt the skill on their paper, white board, or on the provided foldables. Two Foldables can be printed from the Powerpoint so students can keep track of the steps, attempt and example, and write down the strategy.
I wrote tips about using the foldable in your Interactive Math Notebooks, aka Math Journal, in the notes of the foldable slides.
The last few slides have a chant that can help students remember when to use the two strategies. I printed the last slide to put up on my math wall.
I showed this Powerpoint on my Smart Board.
