Intervention Resources
Tier 2 Intervention -- 6.RP.1
Focus Standard:
Understand ratio concepts and use ratio reasoning to solve problems.
6.RP.1. Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.
For example, “The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.”
“For every vote candidate A received, candidate C received nearly three votes.”
Decision Making Guide for 6.RP.1
When and with whom do I intervene around 6.RP.1?
1. Fall: Beginning of the school year for 7th and 8th grade students who have been identified by RIT
scores* that fall within the 6th grade NWEA National Norms and after Critical Point Diagnostic
Assessment has been administered and reviewed.
*Refer to Spring of previous year RIT score.
th
2. Winter: 7 Grade students who are not demonstrating proficiency with 7.RP.1 after Tier 1
differentiated instruction is complete.
3. Spring: 6th grade students that are not demonstrating proficiency with 6.RP.1 after Tier 1
differentiated instruction is complete.
Attending to prerequisite skills:
6.RP.1 builds from the following 4th and 5th grade standards. If student readiness demonstrates a need
to go even further back than 6.RP.1, these are recommended. Follow the links for suggested activities.
Grade 4 – Operations and Algebraic
Thinking
Use the four operations with whole
numbers to solve problems.
4.OA.1. Interpret a multiplication
equation as a comparison, e.g., interpret
35 = 5 × 7 as a statement that 35 is 5
times as many as 7 and 7 times as many
as 5. Represent verbal statements of
multiplicative comparisons as
multiplication equations.

Solve using tape diagrams.
4.OA.2. Multiply or divide to solve word
problems involving multiplicative
comparison, e.g., by using drawings and
equations with a symbol for the
unknown number to represent the
problem, distinguishing multiplicative
comparison from additive comparison.1

Solve using tape diagrams.
Grade 5 – Operations and Algebraic
Thinking
Analyze patterns and
relationships.
5.OA.3. Generate two numerical
patterns using two given rules.
Identify apparent relationships
between corresponding terms. Form
ordered pairs consisting of
corresponding terms from the two
patterns, and graph the ordered
pairs on a coordinate plane. For
example, given the rule “Add 3” and
the starting number 0, and given the
rule “Add 6” and the starting number
0, generate terms in the resulting
sequences, and observe that the terms
in one sequence are twice the
corresponding terms in the other
sequence. Explain informally why this
is so.

Use this activity as a starting point.
Use visual models when possible to
demonstrate the two patterns.
Grade 5 – Number and Operations:
Fractions
5.NF.5. Interpret multiplication as
scaling (resizing), by:
a. Comparing the size of a product to
the size of one factor on the basis of
the size of the other factor, without
performing the indicated
multiplication.
b. Explaining why multiplying a given
number by a fraction greater than 1
results in a product greater than the
given number (recognizing
multiplication by whole numbers
greater than 1 as a familiar case);
explaining why multiplying a given
number by a fraction less than 1
results in a product smaller than the
given number; and relating the
principle of fraction equivalence a/b
= (n × a)/(n × b) to the effect of
multiplying a/b by 1.

Conceptua Big Idea 8 Topics 1-4
address consistently address 5.NF.5.
Topic 3 would be considered a good
review for this standard. The
Multiplying Fractions Tool would also
be appropriate to support this
standard.
