Answer: 4 cans of paint!

*Week 10: Measurement

is for Area

Area helps us find how much paint we need to paint a room! The formula to find area is length x width. Can you help me? I have 4 walls that are 10ft by 5ft. If each can of paint covers 50ft how many cans of paint will I need?

is for Babylonian number system

The Babylonian numeration system was used in 3000-2008 BCE by the people of Babylonia which is modern day Iraq and Syria.

*Week 5: Math is Multi-Cultural

is for Cartesian Plane

The Cartesian Plane was invented by Rene Descartes, a mathematician. It is also referred to as a coordinate plane which you may be familiar with and if has 2 axes which we will learn about later. A Cartesian Plane can help us pinpoint where treasure is on a map using an ordered pair! Hint: (5,5)

*Week 6: Mathematical Inventions

is for divisibility rules

Divisibility rules are shortcuts that help mathematicians like you, work smarter instead of harder! Let's look at the divisibility rules for 9!

Rule: if the sum of the digits are divisible by 9, the number itself is divisible by 9.

Using my rule is 954 divisible by 9?

*Week 1: Multiplication is everywhere

Add 9 + 5 + 4, you get 18, 9 goes into 18, 2 times, therefore 954 is divisible by 9

is for equivalent fractions

Equivalent fractions look different but are the same value. You may need to use equivalent fractions in baking! Maybe you can help me! I am trying to make cookies and the recipe calls for 2/4ths of a cup of flour but I don't have that measuring cup! What other measuring cup could I use? Hint: what number is divisible by both 2 and 4.

*Week 5: math inventions

Answer: I could use the 1/2 measuring cup

is for Fibonacci numbers

Leonardo Fibonacci was a number theorist who discovered the Fibonacci number sequence. The sequence is a series of numbers where each number is the sum of the two preceding number starting with 1, 1, 2,3 etc. Fibonacci numbers do not just exist in math they exist in music and nature too!

*Week 2: Patterns

Answer: 610

is for Gauss

Carl Gauss is a famous mathematician who could add 1-100 very quickly. He would split the numbers into two groups, 1-50 and 51-100. From there he would add the numbers vertically getting a sum of 101 and since there were 50 pairs he multiplied 50 by 101. Can you figure out the sum of adding 1-100 is?

*Week 1: Multiplication is everywhere

Answer: 5050

is for Hindu-Arabic Number System

The Hindu Arabic numeration system is the number system we use in The United States. This numeration system originated in India. It is a base 10 value system and uses 10 numerals. Do you know what we used before this system?

*Week 5: Math is multicultural

Fun Fact: Did you know the numbers have the same amount of angles?

Answer: Roman Numerals

Hint:

is for Integers

An integer is a whole number. Integers are very important when it comes to math. We need integers to do subtraction because integers give us the power to do subtraction.

Can you solve this problem?

7-9=

*Week 3: Algebra is for everyone

Answer: -2

is for John Napier

John Napier is a famous Scottish mathematician who is known for many mathematical achievements. One you may be familiar with is the decimal point, while he did not invent the point itself, he did introduce the idea of using a decimal to separate the whole number from the fraction. Can you write 1/4 using a decimal?

*Week 5: Math inventions

Mathematicians are People too pg 41

Answer: 0.25

is for Konigsberg

Konigsberg is a city in modern day Russia but, there is a historic math problem, the seven bridges of Konigsberg. Citizens wondered whether they could cross the seven bridges at least once. They found a solution does not exist. Thanks to this math problem mathematician Leonhard Euler found that this network has four vertices with an odd degree and cannot be drawn with one continuous stroke leading to the idea of Topology which will be explained later in the book.

*Week 9: Topology may be in your future

is for length

Length helps us with a lot of stuff we need to measure. Length helps us measure distance and objects. It is important to learn all about measurement and all of the different units that go along with length. How long is my pencil?

Week 10: Measurement

Answer: 8 and 1/2 inches

is for metric system

*Week 10: Measurement 1-d, 2-d, 3-d

The metric system is a system of measurement that uses liters, meters, and grams. The metric system is the system that almost the entire world uses. Many people seem to prefer this system because it is easier. All you have to do to convert into another unit is move the decimal! The United States does not use the metric system. Do you know what system they do use?

Answer: The US uses the customary system

is for number line

*Week 1: Multiplication is Everywhere

The number line can help us when adding and subtracting. We go right on the number line to add and left on the number line to subtract. It can help us visually see adding and subtracting in action!

is for ordered pair

Ordered pairs are the notation that tells us where a point goes on a Cartesian or coordinate plane. It is the x coordinate followed by the y coordinate like so: (x,y). They help us with graphing. Can you identify the ordered pair for point A?

*Week 8: Geometry 3d shapes

Answer: (1,0)

is for Probability

*Week 7: Teach probability and fractions together

Probability is in our everyday lives, flipping a coin, playing cards, and many more! Probability is the math that goes behind how likely an event is going to occur. Probability is normally written as a fraction, the denominator being the total amount of outcomes, and the numerator being the chances. Can you tell me how likely you are to land on a red space in the spinner?
