Decimals

__State Standards:__

4.NS.6: Write tenths and hundredths in decimal and fraction notations. Use words, models, standard form and expanded form to represent
decimal numbers to hundredths. Know the fraction and decimal equivalents for halves and fourths (e.g., 1/2 = 0.5 = 0.50, 7/4 = 1 3/4 = 1.75).

4.NS.7: Compare two decimals to hundredths by reasoning about their size based on the same whole. Record the results of comparisons with the symbols >, =, or < , and justify the conclusions (e.g. by using a visual model).

In fourth grade students are introduced to decimals. Students seem to grasp this concept better than fractions. We worked on understanding what a a decimal is and how to represent decimals with manipulatives, pictures, and on a number line. Students will write decimals in standard form, word form, expanded form, and as a fraction. These are the same forms students practiced writing whole numbers in earlier in the year.

We will also learn how to compare decimals. We will work on comparing decimals with manipulatives, pictures, and on number lines.
