 Effective Teaching Strategy
Overview
The lesson will provide students an opportunity to solve algebraic word
problem equations.
Objectives
Students will be able to:
 Solve word problems using algebraic addition and problem solving
strategies.
Vocabulary
Equation, addition, weight, scale, strategies
Prior Knowledge
Students are able to:
 Apply problem-solving strategies.
Consideration for Ell and Migrant  Use of manipulatives.
Students
 Terminology in primary language of ELL student.
Materials
 Manipulatives
 Paper
 Pencils
 Visuals/pictures
Into
Review the problem-solving method or process that students can apply to
 Connect to Prior Knowledge
help them solve word problems.
 Develop Questions
 Modeling
FIND OUT – Look at the problem.
 Have you seen a similar problem before?
 If so, how is this problem similar? How is it different?
 What facts do you have?
 What do you know that is not stated in the problem?
CHOOSE A STRATEGY – How have you solved similar problems in the past?
 What strategies do you know?
 Try a strategy that seems as if it will work.
 If it doesn’t, it may lead you to one that will.
SOLVE IT – Use the strategy you selected and work the problem.
LOOK BACK – Reread the question.
 Did you answer the question asked?
 Is your answer in the correct units?
 Does your answer seem reasonable?
Discuss the base vocabulary and how algebra and problem solving
strategies can aid in solving word problems.

 Strategies
 Visual Representation
 Manipulative
You are given 5 bales of hay. Two bales are weighed at a time, which equal
the following weights:
110, 112, 113,114,115,116,117,118,120,121.
What does each individual bale weigh?
I am assuming that these weights are in pounds. Suppose that the bales
are labeled a,b,c,d,e from lightest to heaviest. The ten pairs of bales are;
ab, ac, ad, ae
bc, bd, be
cd, ce
de
Notice that each bale appears four times in the list above and thus the sum
110+112+113+114+115+116+117+118+120+121=1156
adds each bale four times. Hence the total weight of the five bales is
1156/4 = 289 pounds.
Since a and b are the lightest bales they must together weigh 110 pounds.
Since d and e are the heaviest balse they must together weigh 121 pounds.
Thus bale c weighs 289 - 110 - 121 = 58 pounds.
Can you now find the weights of the other four bales?

 Reflection
 Next steps/Application
Assessment
Metacognitive Reflection
 Ask students how they solved the problem. Can they show how they
arrived at their answer?
 Have students solve the “PUMPKIN CROP” word problem.
 Informal assessment of the students as they work on the problem.
 Circulate and monitor their progress, review their work and strategies.
 Utilize questioning strategies that will engage the students in high level
thinking skills.
 In what way can manipulatives be used for solving problems?
 How might they go about choosing the appropriate strategy?
 How can non-English speakers be involved in the lesson?
