Solve two-step word problems involving multiplication, addition, and subtraction.
The core standards covered in this lesson
4.OA.A.2 — Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.
4.OA.A.3 — Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
The foundational standards covered in this lesson
4.NBT.B.4 — Fluently add and subtract multi-digit whole numbers using the standard algorithm.
3.OA.D.8 — Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding. This standard is limited to problems posed with whole numbers and having whole-number answers; students should know how to perform operations in the conventional order when there are no parentheses to specify a particular order (Order of Operations).

25-30 minutes
Act 1: Look at the following image -
a. What do you notice? What do you wonder?
b. How big was the winning pumpkin? How much money did the winner earn? Make an estimate.

Act 2: Use the following information to determine how much the winner earned -
Act 3: See the solution shown in the original news article.
Was your estimate reasonable? Why or why not?
Act 4 (sequel): Here is another winner of a pumpkin weight contest -
How much money did this winner earn?

Problem Set
A task that represents the peak thinking of the lesson - mastery will indicate whether or not objective was achieved
5-10 minutes
Stan, Denise, and Tyrell all collect coins. Stan has 137 coins in his collection. Denise has 4 times as many coins in her collection as Stan does. Tyrell has 218 more coins in his collection than Denise does.
The Extra Practice Problems can be used as additional practice for homework, during an intervention block, etc. Daily Word Problems and Fluency Activities are aligned to the content of the unit but not necessarily to the lesson objective, therefore feel free to use them anytime during your school day.
Extra Practice Problems
Help students strengthen their application and fluency skills with daily word problem practice and content-aligned fluency activities.
