Unit 5: Fractions and Decimals
Information about the UnitStandards:4.NF.5 Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100. For example, express 3/10 as 30/100, and add 3/10 + 4/100 = 34/1001 .
4.NF.6 Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram. 4.NF.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 the comparisons with the symbols >, =, or <, and justify the conclusions, e.g. by using a visual model. 4.MD.2 Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale. Students should be able to demonstrate the following skills by the end of the unit.: ● Recognize and represent that the denominator determines the number of equal sized pieces that make up a whole. ● Recognize and represent that the numerator determines how many pieces of the whole are being referred to in the fraction. ● Compare fractions with denominators of 2, 3, 4, 6, 10, or 12 using concrete and pictorial models. ● Understand that a decimal represents a part of 10 Lessons in the Textbook
