First, students will learn how to compare decimals, to tenths and hundredths, using shaded grids and number lines.

Watch these Khan Academy videos:

Next, students will learn how to compare and order decimals, to tenths and hundredths, where the numbers being compared are in one of the following forms: a phrase, such as "2 tenths," a decimal number, such as 0.03, a fraction, such as 8/100, a mixed number, such as 2 17/100, and shaded grids. Note that all fractions will have a denominator of 10 or 100, so that students can mentally convert such fractions and mixed numbers to decimals.

4.NF.C.7: Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual model.
