INTERVENTION STRATEGY:
SIR RIGHT
Brief Description: This mnemonic strategy is designed to improve students’ math
problem-solving skills. It cues students through the steps to follow to solve word
problems effectively.
Materials Needed:
Cue cards printed with mnemonic and what it stands for
Classroom posters printed with mnemonic and what it stands for
Implementation: This strategy can be implemented individually, in small groups, or
whole group. It can be facilitated by a teacher, paraprofessional or adult volunteer.
The following steps should be taken when introducing any mnemonic strategy:
1. Discuss the purpose of this strategy and model when to use it.
2. Model what each letter in the mnemonic stands for and how it relates to solving
the math problem.
3. Model how to apply it to what students have already learned about solving
problems.
4. Provide students with cue cards printed with the mnemonic to place on their desks
or to place in their math folders.
5. Put up posters of the mnemonic on the walls of the classroom.
6. Use rapid-fire verbal rehearsal to help students remember the strategy.
Create posters and cue cards with these steps:
S = Start by reading the problem
I = Identify all numbers (digits and words)
R = Reread the problem and draw a picture or diagram
R = Reread the problem again to find the question
I = Inquire, “What do I have to do to answer the question?”
G = ‘Guesstimate,’ or estimate, an answer
H = Have a go at computing an answer
T = Take a check back to see if the answer makes sense
Students should check off each step as it is completed.
Schedule for implementation: The procedure should be taught until students have
mastered the steps and use the strategy independently. Reinforcement of the strategy
should occur daily.
