TEKS 4.5A: Multi-Step Problems with Operations
Multi-Step Problems Using Strip Diagrams
About this lesson
Learning Target: I can represent multi-step problems using strip diagrams.
Focuses On:
- Adding the missing values to strip diagrams that represent multi-step problems involving the four operations with a letter standing for the unknown quantity
- Choosing strip diagrams that represent multi-step problems involving all the operations with an unknown quantity
Builds On:
3.5A:
Represent one‐ and two‐step problems involving addition and subtraction of whole numbers to 1,000 using pictorial models, number lines, and equations.
3.5B:
Represent and solve one‐ and two‐step multiplication and division problems within 100 using arrays, strip diagrams, and equations.
Next Level:
5.4B:
Represent and solve multi‐step problems involving the four operations with whole numbers using equations with a letter standing for the unknown quantity.

This lesson is designed to support student understanding of the steps necessary to solve multi-step problems when there is a given variable by using strip diagrams.
The two instructional blocks in this lesson are missing parts and missing total.
The first instructional block has students completing the missing parts of strip diagrams that represent a multi-step word problem with a letter standing for an unknown quantity.
The second instructional block progresses as students select the strip diagrams that represents word problems with different scenarios, but similar numbers.
Visual models are built into the lesson to support student understanding.

This lesson is designed to support student understanding of the steps and equations necessary to solve multi-step problems when there is a given variable.
The two instructional blocks in this lesson are two equation and three equation problems.
The first instructional block starts with students completing the missing parts of two equations or choosing the equations that represent a multi-step word problem with a letter standing for an unknown quantity.
The second instructional block progresses in difficulty as students determine the three equations needed to represent a word problem involving a letter representing an unknown value. Finally, students must determine the operations necessary to represent the multi-step problems.
This lesson can be taught alongside: "Multi-Step Problems Using Strip Diagrams." It works in conjunction with 4.4A,D,F,H.
Partially completed equations are built into the lesson to support student understanding.
