Free Grade 6 mathematics teaching kit

Compare Unit Rates on the Same Basis

Is this the right resource?

Audience / fit
Grade 6 math
Teaching or planning target
Choose a defensible comparison by finding rates with the same units and direction, then interpret the result for the stated goal.
Essential prerequisites
For Grade 6 mathematics. Begin here when students can interpret a requested unit rate and its units. Otherwise, start with Find and Interpret “Per One”.
Preparation
Read the Start Here selections; preparation time depends on the selected route.
Use time
Use the teacher guide to plan the selected route
Materials
Paper and pencil. Optional counters for equal groups. No device, purchase, account or email is needed.
What to print
Use the stage-specific student choices below and the matching teacher guide. Give independent, new-evidence and later-assessment pages only at their intended stage.

Start teaching

Use readiness to check per-one meaning, then teach with the separate lesson and practice. Compare the same units in the same direction. Give the independent check only after practice; totals alone and a missing time cannot establish a fair rate comparison.

Editable Word, browser copies and other files

Print and adapt for your own planning and classroom use; printed copies may be shared within your classroom or school team, provided the source is not sold. Keep attribution and resource-specific notices. For redistribution and third-party materials, read the Terms of Use. Recommend this resource using its page link.

Choose a stage and format

Give only the stage being used. Keep later tasks and all teacher keys with the teacher until needed.

Formats and all files

Complete reference files may include teaching, independent tasks, later evidence or teacher answers. Keep them with the teacher; use the separate stage selections above for handouts.

Compare rates with the same units and direction, explain ties and missing information, and check whether totals could mislead.

Choose what to give learners

  1. Give Readiness alone before showing the model, glossary or lesson.
  2. Teach the Model and guided lesson, then give only the separate Independent check. The lesson and check use different problems.
  3. Use the teacher guide to choose one supplied continue, clarify, reteach or extend task. Give only that route file.
  4. Reserve the follow-up check, Later revisit and Transfer files until their intended occasion. Previously shown tasks are practice, even when completed independently.

Keep answer keys with the teacher. Note which tasks students have already seen, the tools and support they used, and how they responded. Keep student notes locally. The Start Here guide explains the prerequisites and pages to select across the three kits.

Use the response to choose a next move

Look separately at calculations, unit labels, direction and explanation. Clarify an unclear response before choosing a practice task. After practice, collect students’ responses to a follow-up task, noting any support used.

Scope, sources and reuse

Interpret per one, preserve direction and units, compare on the same basis, explain ties and missing information, and apply a stated constant rate. No percent, measurement conversion, coordinate graphing, complex fractions or complete proportionality course. These kits address 6.RP.A.2 and selected unit-rate applications from 6.RP.A.3b; they do not assess the whole standard or a complete mathematics course.

Teachers may print, use and adapt these original materials for their teaching. Retain Mentor Teaching attribution and identify local changes. Numerical data and examples are constructed, not classroom observations.

Use the editable files to adapt the materials to your learners and local curriculum.

When the lower unit price does not buy the cheapest whole packs

A learner may calculate dollars per item correctly and still choose an infeasible or more expensive purchase. This companion teaches the missing step: find the least number of whole packs that supplies enough, compare total cash paid and qualify the decision for the stated need.

Use it after common-basis unit-price teaching when student work overlooks a pack restriction. The fictional starting response helps distinguish that reasoning from unclear units, an arithmetic slip or an access difficulty. The lesson supplies a teacher model and targeted practice; different follow-up orders test the explanation before a later whole-roll transfer.

  1. Read Start Here and the teacher guide. If entry reasoning is unknown, give Starting task alone.
  2. Choose Lesson and practice after interpreting the response. Use the worked purchase and guided complete-pack counts, then change the quantity needed to challenge an automatic supplier choice.
  3. Keep Follow-up check and Later transfer unused until their intended occasion. Previously shown or helped work is practice. Keep answers with the teacher.

Student pages to select

Download the whole-pack companion and selected comparison first teaching. The ZIP includes all companion PDF, native Word and HTML files plus the unchanged comparison lesson and teacher guide. The original unit-rate collection above remains available with its existing checks. Share selected student pages, not the whole ZIP.

Teacher orientation for choosing whole-pack purchase teaching
Teacher preparation preview; later task amounts and answers are kept separate.

For selected Grade 6 learners who can interpret unit price and multiply whole groups. Read-aloud, enlarged text or an agreed oral or drawn response can preserve the target; supplying pack counts or a supplier choice changes what is checked. Record the support used. The transfer adds measured length; no comprehensive grade coverage or equal-difficulty claim is made.

Prices and learner examples are fictional teaching material. Teachers may print and adapt the original companion under the Terms of Use; retain attribution and identify local changes. Word copies may reflow after editing, so check print preview. Classroom effectiveness has not been established. Report a resource issue.

Use familiar practice beyond the lesson

Keep this lesson’s target when preparing familiar practice beyond the lesson. Prepare a substitute handoff with the exact student pages and return instructions. Plan neutral directions and representation supports that preserve the mathematics. Offer a brief family conversation about practice already taught.

Keep teacher keys and later checks with the teacher. Previously shown or helped work is practice; record the support before interpreting a response.
