Unknown Number In An Addition Or Subtraction Equation
Teacher will say, “We are going to identify the unknown number in an addition or subtraction equation.” Teacher will write a balance equation on the white board, “7 + 6 = 10 + c” and draws small circle on each side. To find the unknown number we have to follow these steps: Step #1: Add or subtract and write the answer of each side in the circle below, Step #2: Find the missing number and write it in the square, Step #3: Make sure both sides of your equation match one another.” Teacher will say, “Let us do this problem together. First, add 7 + 6 =13, write 13 in the circle below. Then, determine what plus 10 is 13? What number?” Someone raise their hand and tell me 10 plus what are 13?” If the student say “3”, then teacher will say, “Correct,

537 Words | 3 PagesHis parents could require him to work out five word problems, with a goal that he work out four out of five (80%) correctly before moving on to higher level problems. As his math and applied problem fluency increases, the problems could be harder and the number of problems per session can be increased (7, 8, 9, 10 word problems per sheet). The focus can still be on 80% of the problems correct even as the difficulty and quantity of problems increase. This is based on “Standard - CC.2.1.4.B.2 Using place value understanding and properties of operations to perform multi-digit arithmetic” and “Standard - CC.2.1.5.B.2 extending an understanding of operations with whole numbers to perform operations including

We need to use technology in the mathematics classroom to help improve our teaching strategies. The study leans towards a student using paper and pencil to a point and then turning to a graphing calculator to do the more mundane calculations. The CAS should be used as a tool to solve a problem that has been evaluated by the students and the appropriate technology chosen. By organizing the many different slight changes in a graph the student may be able to make a prediction about what is expected.
