Once I label my whole number line, I can see that my potato head is located on 0.64!Īs children work on modeling decimals using number lines and decimal grids their knowledge of decimal place value will grow.Įnjoy this time of learning and exploring with them. And I know that 20 x 5 = 100, so I’m going to count up by 2 hundredths. coordinate grid A reference frame for locating. How can I get from five-tenths to six tenths in just five hops? Well, I definitely will be using hundredths. words and numerals, they represent decimals on grids and on number lines.

Now, we have to figure out the lines in-between. If you said, that six-tenths is in the middle, you are correct. (PSTs) used rectangular area models on base-10 grid paper to begin making sense of multiplication of decimal fractions. Let’s start by labeling the fifth hop or the line directly in the middle of five-tenths and seven-tenths. This requires a little more thought process but is very possible. You could represent 12.57 with 12 fully shaded grids and the first grid shown above. Once again there are 10 hops between the two numbers. Use this area model to explain which number is greater. The first number we are given is five-tenths and the final number is seven-tenths. Example 1 : Model 0.78 by shading a 10-by-10 grid.

This number line has different intervals. Provide a new way to understand equivalence and fractional computation This set is color-coded by family, and each grid shows a specific. Using models can help us to understand how decimals, fractions, and percent are related.
