<strong>Horizons</strong> <strong>Math</strong> 6 SAMPLE<br />
Lesson 45<br />
Concepts:<br />
Square roots, exponents, prime and composite numbers, factor trees, six digit<br />
subtraction, five digit by five digit multiplication, logic problems.<br />
Objectives:<br />
1. The student will be able to write, calculate, and interpret square roots.<br />
2. The student will be able to write, calculate, and interpret exponential information.<br />
3. The student will be able to identify prime and composite numbers.<br />
4. The student will be able to create and complete factor trees for given numbers.<br />
5. The student will be able to subtract six digit numbers.<br />
6. The student will be able to complete multiplication problems which contain five<br />
digit factors.<br />
7. The student will be able to correctly complete a given logic problem.<br />
Teaching Tips:<br />
Materials, Supplies, and Equipment:<br />
1. Snap blocks<br />
2. Calculator<br />
3. Worksheet 24<br />
Activities:<br />
1. Read Lesson 45 Explanation together as a class. Use the snap blocks to<br />
demonstrate the sample problems shown in the lesson explanation. Have the<br />
students “play” with the snap cubes and find other squares & square roots.<br />
2. Use the calculators at tools to find the square roots of given numbers. Explain the<br />
student can make educated guesses when looking for a square root. They can then<br />
use the calculator as a resource. For example: When looking for the square root of<br />
121 think about the times tables. If the students know that 10 is the square root of<br />
100, then the square root of 121 should be close to 10. In fact the square root of 121<br />
is 11. Practice find the square root of the following numbers as a class: 289, 324,<br />
10,000 (answers: 17 2 , 18 2 , 100 2 ).<br />
3. Assign Lesson 45-1 as independent work.<br />
