G3+Math+Unit+1

** Investigations Math ** ** Grade 3 ** ** Unit 1: Trading Stickers, Counting Coins ** 1: Make sense of math problems and persevere in solving them. 2: Reason abstractly and answer quantitatively. 4: Model with mathematics. 6: Attend to precision. 7: Look for and make use of structure. 8: Look for and express regularity in repeated reasoning. 3.MD.3, 3.M.4: Represent and interpret data. EfS: B- Responsible Local and Global Citizenship, C- Dynamics of Systems & Change, E - Healthy Commons, F - Natural Laws and Ecological Principles || How can we build our knowledge of number systems and develop computational fluency to help us in everyday life? || Students represent the place value of numbers by using a base 10 model, money, hundred grid and number line. They add and subtract multiples of 10s and use knowledge of place value to find combination with a sum of 100 and 200. || Investigation 2: Working with 100. Students solve addition, subtraction and missing addends problems that involve combination with the sum of 100, using money and other contexts. They find equivalent ways to show quantities with 100s, 10s and 1s and review addition combination up to 10+10 || (Prior Knowledge) || Place value to 100, basic adding and subtracting, adding 10’s || Place value to 100, basic adding and subtracting, number equivalencies || Time Frame Sept 6- Oct 5, 2012 || 9 days || 8 days || 1.8 – Sticker Combinations 1.9 – Investigation Assess of 100’s, 10’s, 1’s || 2.1 – Combinations I Know 2.5 – Addition Combinations 2.8 – End of Unit Portfolio – Differentiated piece - 100’s grid activity ||
