Though it is listed under the NCTM strand of Numbers and Operations, a facility with fractions and their other representations supports students’ understanding of geometry, measurement, probability, and the more complex algebra work that they are just beginning to undertake. This book is designed to reinforce the conceptual understanding of nonwhole numbers. The activities cover 16 key skills that progress from basic (finding equivalent fractions) to complex (converting fractions to percents). By using Sudoku puzzles to frame the problems, practicing these important skills becomes more fun and far more rewarding. You can replace most rote facts-practice worksheets with the 41 leveled Sudoku puzzle challenges in this collection. A key advantage to using these puzzles is that the puzzles are self-checking. If students make an error, they will quickly find that the puzzle isn’t working, which will help them catch the mistake and try to correct it themselves. S UDOKU Name ___________________________ ____________________ Date _________ ________ Directions LEvery These puzzles can be used flexibly. You may want to hand out copies of the puzzles for a warm-up activity (or “do now”) to start class. However, they can also be given to students who finish their class work early or occasionally serve as homework. Students who are struggling can use the Skills Reference Sheet (pages 5 and 6) to help them remember basic concepts. Be sure to model specific skills for individual students or solve puzzles on the overhead or the interactive whiteboard for the class. The tips included at the bottom of some of the Sudoku puzzle pages may also provide helpful hints about the target skill. 1 3CHOLASTIC4EACHING2ESOURCES LFill Decimals s©BY%RIC#HARLESWORTHs Have students who are ready for a challenge solve the Word Problems that appear at the bottom of some of the puzzle pages. You may also invite them to use a 4-by-4 grid to create their own Sudoku puzzle for their peers.

Multiply the whole number by the numerator. 1. Line up your decimal points. 2. Add zeroes to hold place values, if needed. 3. Complete the operation. 2 Example: What is 3 of 60? Example: 2.3 + 2.41 Answer: First multiply: 60 × 2 = 120. Then divide: 120 ÷ 3 = 40. Converting Fractions to Decimals 1. Convert to an equivalent fraction with a denominator to a power of ten. 2. Write the fraction as a decimal. 4 2 8 = Examples: 5 × = 0.8 2 10 7 5 35 × = = 0.35 20 5 100 Decimal 3 4 1 2 2 5 1 4 1 5 1 10 0.75 0.5 0.4 0.25 0.2 0.1 2.30 + 2.41 7.65 − 4.20 4.71 3.45 Multiplying Decimals 1.
