This resource is from Tools 4 NC Teachers. It provides teachers with Norms and guidelines for Number Talks. This can be used for multiple grade levels. It can be remixed.

This short video and interactive assessment activity is designed to teach fifth graders about adding and subtracting - missing number.

This short video and interactive assessment activity is designed to teach fifth graders about adding and subtracting with parentheses - missing number.

This task provides students the opportunity to have some freedom in manipulating numbers while considering the operations and their properties. Students' varied responses should prompt productive mathematical discourse.

Students will understand the importance of the order of operations. Students will understand how the placement of parenthesis and brackets change the order of operations in an equation.

Solve whole number applications with a problem-solving process

This problem asks the student to evaluate six numerical expressions that contain the same integers and operations yet have differing results due to placement of parentheses. It helps students see the purpose of using parentheses.

In this lesson, students will compare the responses when using paranthesis and not using paranthesis when evaluating an expression.

This problem allows students to see words that can describe the expression. Additionally , the words (add, sum) and (product, multiply) are all strategically used so that the student can see that these words have related meanings.

In this task, students are provided with a scenario and asked to write an expression to represent the number of guests that can be seated at 57 tables. The mathematics task is intended to be a problem or question that encourages the use of mathematical practices. The dialogue is meant to show how students might engage in the mathematical practices as they work on the task.

In this lesson, students will be able to explain and apply the criteria used to evaluate both mathematical strategies and computer programming and how the two are related. The criteria for both will be based on efficiency (speed) and effectiveness (accuracy).

For this task, students model multiplication using connecting cubes and connect this concept to volume of a rectangular prism. This activity prompts students to consider both the associative and commutative properties of multiplication.
