2.M.3 RTI Lessons

Misconceptions and errors may result if students don’t understand how the size of a unit relates to the number of units needed to measure a length. Errors may also result if students:

• assume the larger/longer a unit is, the more that are needed to measure a length.
• think inches are smaller/shorter than centimeters.
• confuse units (e.g., inches with centimeters or feet with yards).
• misalign the ruler or use the wrong ruler when measuring a length.

Practice and Building Confidence

Help students pay careful attention to the words and the numbers in each problem. Build confidence with independent practice with measuring/comparing different units.

Review the questions students missed on the assessment. This will help you find the misconceptions they have and specifics on their weaknesses, which may help guide your RTI teaching. The video below will show you how to find their test results and access the test questions.

These are the recommended lessons, in order, to build these students from their current level toward grade level. Use your professional judgement in choosing which pieces to use and the appropriate pace for the students in your group.
