Operations/Computation

Instructional Strategies

  • Use the Interleaved Solutions strategy to teach students computational procedures.
  • Have the student estimate solutions before solving to self-check reasonability of the answer.
  • Ensure the student understands the meaning of the operational symbols.
  • Teach the student to complete problems of one type across an assignment before switching to another type.
  • Have the student highlight the operational symbol in each problem prior to solving.
  • Provide the student with solved problems, some of which are correct and others that are incorrect. Have the student identify the incorrect problems and the mistake made.
  • Provide the student with a mnemonic to scaffold the steps of an operation or have the student create his/her own. E.g. COSMIC for algebraic problem solving, PEMDAS for order of operations, RIDE or STAR for word problems, RENAME for addition and subtraction.
  • Teach students operations using the CRA progression: Concrete, Representational, Abstract.

Scaffolds

  • Allow the student to check his/her work with a calculator.

Operations/Computation

Student will increase accuracy in replacing variables in algebraic equations and solving from 45% accuracy to 80% accuracy as measured by a problem set by December 2019.

 

Teach the student the steps to the COSMIC strategy. Have the student use the checklist to complete the strategy, fading direct teacher support as student gains independence with each step (either fading from the first step on or backwards from the last step).

Computation/Operations with Fractions Student will improve the use of all 4 operations with fractions from 40% to 80% as measured by a set of 10 mixed problems by April, 2020.

Provide student will procedural outline, to be faded over time.

Utilize the CRA sequence to teach understanding of operations with fractions.
