Related Calculations - Worksheet

The "Related Calculations Worksheet" is a comprehensive resource for reinforcing mathematical concepts involving multiplication, division, and the understanding of number relationships. It includes a variety of exercises such as using arrays to complete number sentences, determining the value of number pieces when each dot represents a certain value, and matching number statements to arrays. For example, one task asks students to calculate the total number of sweets in jars when each jar contains a set number of sweets. Another exercise prompts students to identify whether given mathematical statements are true or false, such as if the product of one multiplication is ten times greater than another, or if a division statement is accurate based on known multiplication facts.

The worksheet also challenges students to use fact families to complete related calculations and to explain their thinking when comparing the size of products in multiplication. It encourages the use of arrays to visually prove the equality of different multiplication expressions. Furthermore, students are tasked with scaling up basic multiplication facts to larger numbers, demonstrating their understanding of how increasing one factor by a multiple affects the product. The worksheet is designed to help students develop fluency in multiplication and division, enhance their reasoning skills, and deepen their comprehension of mathematical relationships. Answers are provided to aid in the verification of the students' work and to facilitate discussion on the strategies used to arrive at the correct solutions.
