Grade 4 - Number

Standard 4.N.3 - Simplify both sides of the equation. Fill in the missing number with sums up to 1000 to make the equation true.

Included Skills:

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 = .
