Estimating and finding the difference of whole numbers Mathematics Instructional Plans (MIPs) help teachers align instruction with the Mathematics Standards of Learning (SOL) by providing examples of how the knowledge, skills and processes found in the SOL and curriculum framework can be presented to students in the classroom.
As a teacher your goal is to provide practice using carefully selected strategies. Through encouragement you can provide experiences for students to develop efficient strategies. Use the following strategies to develop the basic addition and subtraction facts. By the end of first grade, students should be able to count on to find the difference. For the difference of 7 - 4, start with 4 and count on 5, 6, 7. This shows that 7 - 4 = three. Another strategy is to use related facts to find the difference. If students use a related fact, 4 + ___ = 7, then they’ll know 7 – 4 = three. Another strategy would be the near doubles strategy. Using the same problem 7 - 4, add 4 + 4 to get 8 and then subtract 1 to get seven.By providing experiences to learn these strategies, students will develop number sense and understand how to compose and decompose numbers. This in turn will help students to develop basic fact fluency and learn while having fun playing a game.
As a teacher your goal is to provide practice using carefully selected strategies. Through encouragement you can provide experiences for students to develop efficient strategies. Use the following strategies to develop the basic addition facts. By the end of first grade, students should be able to counting on to find the sum. For the sum of 4 + 3, start with 4 and count on 5, 6, 7. This shows that 4 + 3 = 7. Another strategy is to use the near doubles strategy to find the sum. Using the same problem 3 + 4, add 3 + 3 to get 6 and then add 1 more to get seven. Or using the same problem 4 + 3, add 4 + 4 to get 8 and then subtract 1 to get seven.By providing experiences to learn these strategies, students will develop number sense and understand how to compose and decompose numbers. This in turn will help students to develop basic fact fluency and learn while having fun playing a game.
Students will find helpful resources for learning and practicing math skills and processes in this eMediaVA collection.
This collection has resources organized by grade level teachers can use to teach math.
A fun dice game to get students excited about figuring out addition and subtraction problems. This activity will help children learn to build greater knowledge of addition/subtraction equations and sums/differences. Studemts are able to exercise and to have fun while building fundamental skills. This activity can also be adapted to multiply and division.
