[FREE] End of Year Math Assessments (Grade 4 and Grade 5)

The assessments cover a range of topics to assess your students' math progress and help prepare them for state assessments.

In order to access this I need to be confident with:

Here you will learn about different types of numbers and how they are related and classified.

Students begin to learn about types of numbers beginning in kindergarten and develop that knowledge from elementary school through high school.

**Types of numbers **are classified into specific number sets. In elementary school, you will work with the** **set** of rational numbers**.

Let’s look at the different types of numbers and how they are classified.

A Venn diagram can also help you see the number sets.

**Special classifications**

**Prime and composite numbers**

A prime number is a number with exactly two factors: itself and 1.
2 and 7 are examples of prime numbers.
2 has 2 factors: 7 has 2 factors: 1, 2 \hspace{2.5cm} 1, 7 1 \times 2 = 2 \hspace{2cm} 1 \times 7 = 7 | A composite number is a number with more than two factors.
4 and 12 are examples of composite numbers
4 has 3 factors: 12 has 6 factors: \hspace{.4cm}1, 2, 4 \hspace{1.9cm} 1, 2, 3, 4, 6, 12 \hspace{.2cm}1 \times 4 = 4 \hspace{1.7cm} 1 \times 12 = 12 2 \times 2 = 4 \hspace{1.7cm} 2 \times 6 = 12 \hspace{3cm} 3 \times 4 = 12 |

**Even and Odd Numbers**

Even numbers are divisible by 2 without remainders; they end in 0, 2, 4, 6, or 8. | Odd numbers are not divisible by 2 without remainders and end in 1, 3, 5, 7, or 9. |

**Positive and negative numbers**

Positive numbers are numbers that are greater than 0. On the number line, they are to the right of 0. Positive numbers can be whole numbers, fractions, or decimals. |

Negative numbers are numbers that are less than 0. On the number line, they are to the left of 0. Negative numbers can be whole numbers, fractions, or decimals. |

**Fractions**

Fractions are numbers that are equal parts of a whole. They have a numerator and a denominator separated by a fraction bar. Fractions can also be interpreted as division. Numerator → dividend Denominator → divisor Fraction bar → division bar Types of fractions:Proper fractions are fractions where the numerator is less than the denominator.For example, \, \cfrac{2}{3} \, is a proper fraction. Improper fractions are fractions where the numerator is greater than the denominator. For example, \, \cfrac{4}{3} \, is an improper fraction. Mixed numbers (mixed fractions) are an integer with a proper fraction. For example, \, 1\cfrac{1}{3} \, is mixed number. |

**Decimals**

Decimals are numbers that are similar to fractions. They have a whole part and a fractional part that are separated by a decimal point.Our decimal system splits whole numbers into tenths, hundredths, thousandths, and so on. For example, 1.21 is a number in decimal form. It can be represented on a place value chart. 1.21 can also be represented with place value blocks. Types of Decimals1.21 is the same as 1\cfrac{21}{100} = \cfrac{121}{100} 0.33333… or 0.\overline{3} is a repeating decimal. The bar above the digit 3 means that 3 is repeating. Repeating decimals can be represented as a fraction. 0.\overline{3} is the same as \cfrac{1}{3} cannot be represented as a fraction. \pi , (pi) is a non-repeating, non-terminating decimal. \sqrt{5} ( square root of 5 ) is a non-repeating, non-terminating decimal. |

**Square and Cube Numbers**

A square number is the result of multiplying a number by itself. For example: 1 \times 1 = 1 → 1 is a square number 2 \times 2 = 4 → 4 is a square number 3 \times 3 = 9 → 9 is a square number 1 \times 1 can be written in a shorter way, using an exponent. 1^2 2 \times 2 can be written in a shorter way, using an exponent 2^2 3 \times 3 can be written is a shorter way, using an exponent 3^2 | A cube number is the result of multiplying an integer by itself three times. For example: 1 \times 1 \times 1 = 1 → 1 is a cube number 2 \times 2 \times 2 = 8 → 8 is a cube number 3 \times 3 \times 3 = 27 → 27 is a cube number 1 \times 1 \times 1 can be written in a shorter way, using an exponent. 1^3 2 \times 2 \times 2 can be written in a shorter way, using an exponent 2^3 3 \times 3 \times 3 can be written is a shorter way, using an exponent 3^3 |

**Reciprocals**

The reciprocal of a number is the multiplicative inverse of a number.
Meaning that when the reciprocal of a number (multiplicative inverse) is multiplied to the given number, the result is 1. For example, the reciprocal of 5 is \, \cfrac{1}{5}. 5 can be written as \, \cfrac{5}{1} \, to find the reciprocal, flip the numerator and the denominator. So, \, \cfrac{5}{1} \, will become \, \cfrac{1}{5}. The reciprocal of \, \cfrac{1}{2} \, is \, \cfrac{2}{1}. |

DOWNLOAD FREEIs 1\cfrac{3}{4} \, a rational number?

**Recall the definition of the type of number needed.**

By definition, a rational number is any number that can be expressed as a fraction where the numerator and denominator are integers.

2**Show that the number fits or does not fit in the number set or definition.**

1\cfrac{3}{4} \, is a mixed number. A mixed number can be written as an improper fraction.

The model shows 1\cfrac{3}{4}.

The first circle model shows 4 shaded parts out of 4 equal parts, which is \, \cfrac{4}{4} \, or 1.

The second model shows 3 shaded parts out of 4 equal parts which \, \cfrac{3}{4}.

\cfrac{4}{4}+\cfrac{3}{4}=\cfrac{7}{4}

\cfrac{7}{4} \, is a rational number because the numerator and the denominator are both whole numbers

\cfrac{7}{4} \, is the same as 1\cfrac{3}{4} \, → is in the rational number set

Also, rational numbers include all positive and negative mixed numbers.

Determine whether the number 23 is a prime number.

**Recall the definition of the type of number needed.**

The definition of a prime number is any positive whole number that has only two factors, 1 and itself.

**Show that the number fits or does not fit in the number set or definition.**

The factors of 23 are 1 and 23. 23 is a prime number.

Is 15 an odd number?

**Recall the definition of the type of number needed.**

Odd numbers are not divisible by 2 without remainders and end in 1, 3, 5, 7, or 9.

**Show that the number fits or does not fit in the number set or definition.**

15 ends in a 5, it is an odd number.

Find the reciprocal of 14.

**Identify the numerator and denominator of the given number.**

14 can be written a the fraction \, \cfrac{14}{1} \, because all whole numbers can be written in this form.

The numerator is 14 and the denominator is 1.

**Flip the numerator and the denominator.**

\cfrac{14}{1} \, will become \, \cfrac{1}{14}.

The numerator becomes the denominator and the denominator becomes the numerator.

**Multiply the given number by the reciprocal to check that the product is **1 **.**

\cfrac{14}{1}\times \cfrac{1}{14} = \cfrac{14}{14}=1

The product of a number and its reciprocal is always 1.

Determine if 16 is a square number.

**Recall the definition of the type of number needed.**

A square number is the result of multiplying an integer by itself.

Let’s start with 1.

\begin{aligned}
&1 \times 1 = 1 \\
&2 \times 2 = 4 \\
&3 \times 3 = 9 \\
&4 \times 4 = 16
\end{aligned}

**Show that the number fits or does not fit in the number set or definition.**

16 = 4\times 4. 16 is a square number.

Show that \cfrac{2}{9} is a repeating decimal.

**Recall the definition of the type of number needed.**

The definition of a repeating decimal is any decimal where the decimal places repeat indefinitely.

**Show that the number fits or does not fit in the number set or definition.**

A fraction can be seen as division where the numerator is the dividend, the denominator is the divisor, and the fraction bar is the division bar.

\cfrac{2}{9} \, is the same as 2 \div 9. Long division is used to divide the numbers.

You can see the repeating pattern in the division and in the answer.

This means that \cfrac{2}{9}=0.22…=0.\overline{2}.

- Use the Venn Diagram to help students make connections between the different types of number sets.

- The number sets build upon themselves from the very first set of numbers they work with which is natural numbers. This will help students understand that natural numbers, whole numbers and integers are all considered to be rational numbers too.

- Using a calculator is helpful when showing elementary students repeating decimals.

- Reinforce to students that the cardinal numbers and positive integers are the same as the set of natural numbers.

**Mixing up the definitions**

It is common to mix up definitions. For example, assuming that whole numbers are natural numbers and vice versa

Example: Whole numbers include 0 and natural numbers do not.

**Thinking zero is a natural number.**

Zero is not a natural number. The natural numbers are considered to be the counting the numbers and starting with 1.

**Thinking whole numbers are not rational numbers.**

Rational numbers are numbers that can be expressed as a fraction where the numerator and the denominator are integers. The number 3 is rational because we can express 3 as the fraction \, \cfrac{3}{1}.

**Thinking that**2**is not a prime number.**

Students often think that prime numbers have to be odd numbers. 2 is a prime number and an even number.

1. 22 is in what number set?

The first model shows 5 shaded parts out of 5 equal parts.

The second model shows 1 shaded part out of 5 equal parts.

\cfrac{5}{5}+ \cfrac{1}{5}= \cfrac{6}{5}

\cfrac{6}{5} \, is a rational number because the numerator and the denominator are both whole numbers.

\cfrac{6}{5} \, is the same as 1\cfrac{1}{5} \, is a rational number.

Also, rational numbers include all positive and negative mixed numbers.

By definition, a rational number is any number that can be expressed as a fraction where the numerator and denominator are integers.

The rational number set includes all positive and negative fractions, decimals, repeating decimals, and integers.

3. What type of number is 2

Improper fraction

Prime number

Composite number

Odd number

2 is a prime number because it only has two factors 1 and 2.

1 \times 2 = 2

4. Find the reciprocal of \, \cfrac{2}{3}.

\cfrac{2}{3}

\cfrac{1}{3}

\cfrac{3}{2}

\cfrac{1}{2}

\cfrac{2}{3} \, has a numerator of 2 and the denominator of 3.

To find the reciprocal flip the numerator and the denominator where the numerator becomes the denominator and the denominator becomes the numerator.

So, the reciprocal of \, \cfrac{2}{3} \, is \, \cfrac{3}{2}

\cfrac{2}{3}\times \cfrac{3}{2}= \cfrac{6}{6}=1

5. What type of number is \, 0.\overline{4}?

Terminating decimal

Non-terminating decimal
