•

## ### Topics covered in Unit 1: I can..

• I can tell the difference between an expression and equation.
• I can recognize or recall exponenets, bases, brace, brackets, parenthesis brackets, and evaluate expressions.
• I can solve expressions without exponents, parentheses, brackets, or braces.
• I can solve exponents with a base of 10.
• I can use parentheses, brackets, or braces in numerical expressions and evaluate expressions with these symbols.

• I can fluently multiply multi-digit whole numbers using the standard algorithm up to a 3 digit by 2 digit factor.
• I can solve multi-step real world problems that may include larger factors.
• I can recognize or recall communitive property, associative property, distributive property, dividend, divisor, and quotient.
• I can divide using single-digit divisors using at least one of the following methods: strategies based on place value, the properties of operations, or the relationship between multiplication and division.
