Unit 1: Writing Assignments

Implementing the CRA Instructional Approach into mathematic interventions is

beneficial in improving the performance of students. Using the 3 part instructional strategy

promote student learning and retentions. The CRA instructional sequence is consist of three

stages: concrete, representation and abstract. In using CRA sequence of instruction it proves a

graduated, scaffold foundation. Example of the mathematical concept (CRA method) is

illustrated below using standard 3.NBT.2, Fluently add and subtract (including subtracting

across zeros) within 1000 using strategies and algorithms based on place value, properties of

operations, and/or the relationship between addition and subtraction. Include problems with

whole dollar amounts (Mississippi College and Career Readiness Standards for Mathematics

Scaffolding Document, 2021).

Question

A farmer was planting vegetables in a garden. He planted 623 corn seeds, 519 turnip seeds and

81 potato seeds. How many seeds did he plant total?

Station 1

At this station we will focus on the concrete phase of the CRA instructional approach .

Students will have access to hands on manipulative. In using the manipulative students will be

able to move objects to represent their thinking. I reference to the question student should be able

to demonstrate their thinking with base ten blocks and hundred tiles to represent the addition

expression. Example: to show 623 students will use 6 hundreds block, 2 tens blocks and 3 ones

blocks.

Station 2

At this station students will focus on the representation phase of the CRA instructional

approach. While at this station students will be able draw their representation. I will also

introduce the hundred grid and have students color their representation from station one on the

grid. Students should be able to make connection to the concrete phase at this station.

Station 3

At this station students will focus on the abstract phase of the CRA instructional approach.

Students will use the prior stations to close the gap by writing out equations to demonstrate the

question. I will show students to cue students the place value of each number. For example I will

show students 6 hundred tiles and cue them to make the connection between the name of the tile

and how many tiles we actually have , leading the students to write six with two zeros ( 600). At

this station I will continue to practice with several examples until the child connects the concrete

blocks to place value and addition.
