G3+Math+Unit+7

** Investigations Math ** ** Grade 3 ** ** Unit 7: Finding Fair Shares ** 1. Make sense of math problems and persevere in solving them. 2: Reason abstractly and answer quantitatively. 3. Construct viable arguments and critique the reasoning of others. 4: Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision. 8: Look for and express regularity in repeated reasoning. 3.OA.3 – Represent and solve problems involving multiplication and division. 3.OA.5 – Understand properties of multiplication and the relationship between multiplication and division. 3.OA.7 – Multiply and divide within 100. 3.NBT.1, 2 – Use place value understanding and properties of operations to perform multi-digit arithmetic. 3.NF.1, 2, 3a-d – Develop understanding of fractions as numbers. 3.MD.1 - Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects. 3.G.2 – Reason with shapes and their attributes. EfS: C – The Dynamics of Systems and Change, D – Sustainable Economics, E – Healthy Commons, F – Natural Laws and Ecological Principles, I – Sense of Place || Students work with unit fractions, looking at parts that make up a single whole as well as sets of objects that are a fraction of a group. Students also begin to use fractions with numerators greater than one. || ** Investigation 2: Many Ways to Make a Share ** Students build their knowledge of fraction equivalencies as they represent whole and fractional quantities with pattern blocks. || ** Investigation 3: Introduction to Decimals ** Students are introduced to decimals (0.50 and 0.25) in the context of money. They compare decimals with their fractional equivalents, continuing to build a repertoire of notations to represent equivalent quantities. || fraction denominator numerator equivalent fractions || 2.1 – 2.4 || 3.1 – 3.4 decimal point decimal || 1.6 Assessment Activity – Sharing Four Brownies || Differentiated Portfolio Piece 2.3 & 2.4 Assessment Activity – Many Ways to Make a Share || 3.2 – pgs. 33-35 3.4 - End of Unit Assessment ||
