G3+Math+Unit+4

** Investigations Math ** ** Grade 3 ** ** Unit 4: Perimeter, Angles, and Area ** 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. 7: Look for and make use of structure. 8: Look for and express regularity in repeated reasoning. 3.NBT.1, 2 - Use place value understanding and properties of operations to perform multi-digit arithmetic. 3.MD.5ab, 3.MD.6, 3.MD.7abd, 3.MD.8 – Geometric measurement: Understand concepts of area and relate area to multiplication and to addition. 3.G.1 – Reason with shapes and their attributes. EfS: C – The Dynamics of Systems & Change, E – Healthy Commons, I – Sense of Place, || Students develop their ability to use measurement tools to accurately measure objects. They learn that perimeter is the distance around the edges of a 2-D figure and that it is measured. || ** Investigation 2: Understanding and Finding Area ** Students identify the amount of space a given object covers as its area, and develop an understanding that area is measured with square units. They use this knowledge to measure an irregular area – their footprint. || ** Investigation 3: Triangles, Quadrilaterals, and Angles ** Students identify various attributes of shapes and learn that the number of sides identifies a shape as a triangle or a quadrilateral. They identify right angles as having a measure of 90 degrees and learn that angle size is independent of figure size. || measurement benchmark perimeter || 2.1 – 2.6 tetromino flip turn slide congruent area || 3.1 – 3.6 vertex/vertices right angle quadrilateral degree parallelogram || 1.4 – Student pages 12, 13 || 2.5 – p. 25 Differentiated Portfolio Task (area) 2.6 – Assessment Make a Shape || 3.2 – Which are Triangles?
