Скачать или смотреть Mastering the Hundred Grid: Representing Percents of All Sizes

To provide a comprehensive lesson, your video should cover three main ways to use a hundred grid, which is a grid of 100 squares where one completely shaded grid represents 100%,:
1. Percents Greater Than 100%: To represent these, you must use more than one grid,. For example, 130% is shown by shading one full grid (100 squares) and 30 squares on a second grid,. To represent a value like 350%, you would shade three full grids and half of a fourth grid.
2. Fractional Percents (Between 0% and 1%): These represent a portion of a single percent. To show this, you can "zoom in" on one square of the hundred grid and divide that single square into smaller sections,. For instance, representing 0.7% involves shading 7/10 of one single square.
3. Real-World Application: You can explain how these concepts appear in daily life, such as reading Recommended Daily Value (RDV) on nutrition labels—where a single glass of juice might contain 130% of your Vitamin C—or understanding interest rates on credit card balances, which are often expressed as fractional percents like 18 ¾%,.
Analogy for Understanding: Think of the hundred grid like a building with 100 rooms. If the building is "100% full," every room has a guest. If you have a percent greater than 100%, you need to add a second building to fit everyone. If you have a fractional percent (less than 1%), it’s like having a guest who is only staying in a corner of one single room—you have to "zoom in" on that one room to see exactly how much space they are taking up
