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.
In this lesson students use an inquiry approach to place decimals on a number line. This lesson requires students to use base ten blocks as decimal models in order to build conceptual understanding.
Proving that a decimal is greater than another decimal is easy after an in depth discussion about common mistakes in thinking, strategies to keep us thinking correctly and having fun drawing on graph paper.
