Horizons Math 6 SAMPLE
Lesson 45
Concepts:
Square roots, exponents, prime and composite numbers, factor trees, six digit
subtraction, five digit by five digit multiplication, logic problems.
Objectives:
1. The student will be able to write, calculate, and interpret square roots.
2. The student will be able to write, calculate, and interpret exponential information.
3. The student will be able to identify prime and composite numbers.
4. The student will be able to create and complete factor trees for given numbers.
5. The student will be able to subtract six digit numbers.
6. The student will be able to complete multiplication problems which contain five
digit factors.

Teaching Tips:
Materials, Supplies, and Equipment:
1. Snap blocks
2. Calculator
3. Worksheet 24
Activities:
1. Read Lesson 45 Explanation together as a class. Use the snap blocks to
demonstrate the sample problems shown in the lesson explanation. Have the
students “play” with the snap cubes and find other squares & square roots.
2. Use the calculators at tools to find the square roots of given numbers. Explain the
student can make educated guesses when looking for a square root. They can then
use the calculator as a resource. For example: When looking for the square root of
121 think about the times tables. If the students know that 10 is the square root of
100, then the square root of 121 should be close to 10. In fact the square root of 121
is 11. Practice find the square root of the following numbers as a class: 289, 324,
10,000 (answers: 17 2 , 18 2 , 100 2 ).
3. Assign Lesson 45-1 as independent work.
