Included Skills: Addition
Demonstrate an understanding of addition of numbers with answers to 10 000 and their corresponding subtractions (limited to 3 and 4-digit numerals) by: • using personal strategies for adding and subtracting • estimating sums and differences • solving problems involving addition and subtraction. • Achievement Indicators • Students who have achieved this outcome(s) should be able to: - Explain how to keep track of digits that have the same place value when adding numbers, limited to 3- and 4-digit numerals. - Explain how to keep track of digits that have the same place value when subtracting numbers, limited to 3- and 4-digit numerals. - Represent concretely, pictorially, symbolically the addition and subtraction of whole numbers up 4-digit by 4-digit. - Describe a situation in which an estimate rather than an exact answer is sufficient. - Estimate sums and differences using different strategies, i.e., front-end estimation and compensation. - Solve problems that involve addition and subtraction of whole numbers (one or more steps/where some numbers may be irrelevant). Explain solutions to problems. - Create a problem given a number sentence for addition or subtraction. - Solve problems that involve addition and subtraction in more than one way, limited to 3- and 4- digit numerals. For example, 385 + = 500 or 500 – 385 = .
