D Investigate math through developing critical thinking skills DBecome familiar with whole numbers, averaging, rounding, and fractions D Identify decimal basics and using decimals in the real world DLearn how to work with percentages in the real world DStudy basics of geometry from pairs to polygons DDevelop maps, graphs and charts, units of measure, and more.

To the teacher: Mathematics and God’s relational character God teaches us through relationships. He is the One who set the example for this principle, using the perfect relationship between the members of the Trinity. He wants a relationship with us (John 3:16). Our children need a good relationship with us — not just for the sake of that relationship, but to lead them to Jesus. We cannot save our children’s souls, but our relationship with our children can build trust and lead them to the One who can. Our children need to know that everything they can learn about the world around them is already known by God.Think about this: the Alpha and the Omega, the Beginning and the End spoke, and His words created, and carried the power to set in motion everything in the world. God, the supreme architect, sent His words into the dark void and created the intricate, tiniest, most minute building blocks of matter, and then He taught them the secrets that keep them joining and bonding and creating larger building

blocks. And in the mix of all of this, He used the part of His wisdom and character that we humans call math. Psalm 19:1 says, “The heavens proclaim the glory of God. The skies display His craftsmanship.”Since God created it, math is a reflection of His character. God is absolute, consistent, and unchanging. No matter how many times His character and promises are tested, they come out true. As we learn about His creation (including operations with numbers!), our faith in His unwavering faithfulness is strengthened.Those of us who are His children can come and ask for wisdom. I hope you have chosen to accept Jesus as your Savior and Friend. If you have, you have the promise that God will help you and give you wisdom (James 1:5). “Fear of the Lord is the beginning of wisdom” (Prov. 9:10). This means that you can ask Him for help with learning!

Math Level 6

Although this course was written mostly for the student, the story segments help the teacher build/strengthen a relationship with each student. The storyline of Math Lessons for a Living Education Book 6 is not merely written to introduce math concepts; it is meant to bring the element of character and relationship to the study of math. Children learn best when they can learn through relationship. The story in this course is prayerfully crafted to reach into many issues that children this age are facing . . . the question of a personal faith in God, the question of trust in God’s goodness even in the midst of hardship, the decision of letting God use pain for their good, etc. Read the story together, knowing that it is our tendency to push our children into independent learning at this age. Although a certain amount of independence is important, it is also extremely important that we maintain an element of closeness. Our children need contact with us more at this age than almost at any other time. Stay close. Stay plugged in. Stay involved.

• The concepts of math are a conversation between your student and the text. This Course is meant to grow your child’s faith in God, critical thinking ability, and confidence in their God-given ability.

• Quiz note: If you have used the previous courses in this series, you are aware that they contain very few quizzes or tests. This is because they are written in such a way that your child is consistently showing you what they know. Book 6 is also written in this way, BUT, because quiz and test taking is a skill that they need in life, they have been added in this teacher guide. If you, as the teacher, do not want your child to take every single lesson quiz, simply use the lesson practice and review. You decide what your student needs and adjust this course to fit them. Please also note that lesson 22 of this course is ten days worth of work on some additional, rather advanced concepts. Please preview this lesson and read the note at the beginning of it. Also note that there is an optional, but highly recommended, two-day student presentation at the end of the book. You may want to tell your student about it, so he or she can be thinking on what to present.

Note: There is a complete list of supplies in the student book.

Rounding tricks

When w

e work w

ith numbers, w

e often need to round them to m

ake it easier to do computations w

ith them. For

example, w

e may need to quickly estim

ate what several large num

bers are all together. It is important to know

the process of rounding and estim

ating. I am

going to teach you some fun tricks to rem

ember w

hen you are rounding, but first let’s review the steps of

rounding.

Example: Round 3

67 to the hundreds place.

Decide w

hat two “hundreds” 3

67 is betw

een. 30

0 and 40

0 U

nderline the digit in the place to which you are rounding. (3)

Trick #1: Ask the neighbor num

ber if you should round to the smaller hundred or the larger hundred. Is the

neighbor number to the right (6) five or bigger? If it is, round to the bigger hundred. If it is sm

aller than five, round to the sm

aller hundred. Trick #2: Turn all the neighbors to the right of the place to w

hich you are rounding into place holder zeros. 367

becomes 4

00

.

Now

you try it: Round these num

bers to the ten’s place. 1.

Addition (short and long)

Num

bers are amazing, aren’t they? Th

ey can show how

many socks w

e own, or they can show

how m

any socks our w

hole family ow

ns. When w

e want to com

bine two or m

ore numbers, w

e use an operation called adding. By adding tw

o numbers (addends) together, w

e come up w

ith an answer called the sum

. Remem

ber, addends may be added in

any order without changing the sum

. Let’s start w

ith a review of sim

ple addition. W

e can add horizontally.

We can add w

ith carrying. In this problem

, when w

e add the one’s column, w

e end up with m

ore than what can fit in the one’s place (a num

ber larger than 9). Th

is means that w

e have to carry the group of ten up to the top of the ten’s column and add it to the

rest of the tens.

Multiplication Basics and M

ultiplication Facts Review

In your previous years of studying m

ath, you have learned that skip counting is another way to learn the factors in a

multiplication fam

ily. When you skip count by 2, you use this pattern:

2, 4

, 6, 8

, 10, 12

, 14, 16

, 18, 2

0…

(1x2) (2

x2) (3

x2) (4

x2) (5

x2) (6

x2) (7x2

) (8x2

) (9x2

) (10x2

)

As you can see, you are adding another group of 2 to each num

ber to get the next number. You are probably very

familiar w

ith counting by 2s . Explain to your teacher how

skip counting is related to multiplication. In the follow

ing problem

s, show how

skip counting and multiplication go together, like I did w

ith the 2s above. 1.

Skip count by 3 to 30: 3

Division basics

You have learned that addition and subtraction are related. In the space below, 1.

Use Your N

oodle — draw

a doodle! showing how

addition and subtraction go together. A

nswers w

ill vary.

2. N

ow, let’s quickly review the concept of division! If you have 6 cookies, and your m

om says, “Th

at’s way too

many! Share half of those w

ith your brother!” How

many cookies w

ill each of you have? 3 That’s division. H

ow

did you do it? Draw

a doodle below. Underneath that, draw

a doodle of how m

ultiplication and division are related. A

nswers w

ill vary.

3. D

o a quick review of your division facts! Study these m

ultiplication facts and write the m

atching division facts that go w

ith them.

Example:

12 x 12

= 144

division: 14

4 ÷ 12

What if you w

anted to divide a dividend by a divisor and the quotient doesn’t come out even? W

hat if there is som

ething remaining? D

on’t worry —

when this happens, you have a rem

ainder! This can happen in sim

ple division equations, as w

ell as long division.Exam

You can use rounding to estimate the quotient of a division problem

by first rounding both the dividend and the divisor before dividing. Exam

ple: 32

1 ÷ 31 =

30

0 ÷ 3

0 = 10

Now

you try it! Round the dividend and the divisor to quickly find the estimated answ

er of each problem.

7. 562 ÷ 12

50

0 ÷

50

= 10

40

0 ÷

40

= 10

Use Your W

ords! Explain the process you worked through in problem

2 of this exercise.A

nswers w

ill vary but should include discussion of long division.

Simply round each num

ber to the nearest largest place value. In this case you are rounding the dividend to the hundred’s place and the divisor to the ten’s place.
