- 1. How to Model Multiplication of Decimals<br />
- 2. To model a whole number times <br />a decimal:<br />Example 3 x 0.2 =<br />
- 3. This is 3 groups of 0.2 so shade<br />in 3 groups of 2 tenths.<br />Example 3 x 0.2 =<br />
- 4. Example 3 x 0.2 =0.6<br />
- 5. To model a whole number times a decimal when the answer is greater than 1 Example 0.4 X 5<br />
- 6. .4 X 5<br />The Answer is 2<br />
- 7. To Model decimal x decimal:<br />Example 0.3 x 0.5 =<br />
- 8. First, shade in the first number vertically.<br />Example 0.3 x 0.5 =<br />
- 9. Second, shade in the 2nd number horizontally.<br />Example 0.3 x 0.5 =<br />
- 10. The area that has been shaded twice<br />is the answer.<br />Example 0.3 x 0.5 = .15<br />
- 11. You try it! 0.5 x 0.4<br />
- 12. You try it! 0.5 x 0.4<br />
- 13. 0.5 x 0.4 = 0.20<br />
- 14. You try it! 0.3 x 0.4<br />
- 15. 0.3 x 0.4 = 0.12<br />
- 16. You try it! 0.8 x 0.9<br />
- 17. 0.8 x 0.9 = 0.72<br />
- 18. You try it! 0.6 x 0.7<br />
- 19. 0.6 x 0.7 = 0.42<br />
