- “Tower Multiplication” worksheet
Goals
- Learn about cell towers;
- Practice multiplication of a multi-digit number by a single-digit number.
Objectives

- Understand that towers are built to hold a maximum amount of weight.
Common Core State Standards
CCSS.MATH.CONTENT.4.NBT.B.5
Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
Next Generation Science Standards
ETS1.A: Defining Engineering Problems
Possible solutions to a problem are limited by available materials and resources (constraints). The success of a designed solution is determined by considering the desired features of a solution (criteria). Different proposals for solutions can be compared on the basis of how well each one meets the specified criteria for success or how well each takes the constraints into account.
ETS1.C: Optimizing the Design Solution
Different solutions need to be tested in order to determine which of them best solves the problem, given the criteria and the constraints.
3- 5-ETS1-1
People’s needs and wants change over time, as do their demands for new and improved technologies.
3-5-ETS1-2
Engineers improve existing technologies or develop new ones to increase their benefits, decrease known risks, and meet societal demands.
