Direct Instruction Lesson Plan: Squares And Square Roots

Direct Instruction Lesson Plan: Squares and Square Roots

Component 1: Preplanning Tasks

A. Connection Analysis: TEKS 7.1C – Students will represent squares and square roots using

geometric models. TEKS 7.13D – Students will select tools such as real objects,

manipulatives, paper/pencil, and technology or techniques such as mental math,

estimation, and number sense to solve problems.

B. Content Analysis:

1. Identify the square of a number and show the relationship between that and the

square root.

2. Prerequisite skills: multiplication, division, exponents, and math involving decimals

3. Key Terms: square, square number, square root, exponent

C. Objective: Students will be given direct instruction involving the relationship between

square and square roots. Students will demonstrate how to find the square and square

roots of pairs of numbers using geo-boards and record their answers in a chart provided

for them.

D. Objective Rationale: Allowing the use of the geo-boards helps students visualize what a

perfect square is and work the math out using easily identifiable numbers so they can

connect the relationships with perfect square numbers, square roots, and perimeter and

area.

E. Materials: 10 X 10 Geo-boards, Rubber Bands, Introduction Transparency, Recording

Chart (one for each student). Non-Squares and Greeks (1 per student)

F. Room Arrangement: Desks are in groups of 2 and all students will be able to see the

board.

Component 2: Lesson Set-Up

A. Gain Attention: Teacher should say “Class” with the understanding that students will

respond with “Yes” and stay quiet to await for instructions. Pass out the geo-boards

and let students have time to play with them by asking questions such as, can you make

a square? A triangle? How many pegs around is the square you’ve made? When we

measure around a square what is that called? How can we find the area of a square?

B. Behavior Expectations: Students stay on task with working with their board and

answering questions out loud. Students experiment with the board on their own, but

focus remains on the board and its relation to math.
