rik draws these models to show 0.7 and 0.07

To visually represent the numbers 0.7 and 0.07, Rik can use models such as base ten blocks, number lines, or area models. Here are a few ways he might illustrate these values: 1. **Base Ten Blocks**: - **0.7**: Rik can use 7 tenths blocks (which are typically long rectangles representing tenths) to show 0.7. This would be a single long block divided into ten equal parts, with 7 parts shaded or colored to represent 0.7. - **0.07**: For 0.07, Rik can use 7 hundredths blocks (which are smaller squares representing hundredths). He would show 7 small squares out of 100 total squares to represent 0.07. 2. **Number Line**: - **0.7**: On a number line, Rik can mark the point for 0.7, which is between 0.6 and 0.8. He can label it clearly. - **0.07**: On the same number line, he can mark 0.07, which is much closer to 0 than to 0.1. This will visually show how much smaller 0.07 is compared to 0.7. 3. **Area Models**: - **0.7**: Rik can draw a rectangle divided into 10 equal parts and shade 7 of those parts to represent 0.7. - **0.07**: For 0.07, he can draw a smaller rectangle divided into 100 equal parts and shade 7 of those parts to represent 0.07. These visual models help to illustrate the difference in magnitude between 0.7 and 0.07, making it clear that 0.7 is ten times larger than 0.07.
