Essential Questions:
Unit 4 instructional time is focused on these power standards:
5.NBT.B.7 Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
5.NF.A.2 Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2.
Unit 4 instruction is supported by these standards:
5.NBT.A.3 Read, write, and compare decimals to thousandths.
5.NBT.B.4 Use place value understanding to round decimals to any place.
5.NF.A.1 Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)
 How can you add the change in you pocket with the change in your friends wallet?
 How can you count how whole candy bars you have when you only have fractions of candy bars?
 Partial numbers can be written as a decimal and as a fraction.
 Partial numbers can be added and subtracted like whole numbers.
