Description |
| Divisibility Rules and Factors: | The students will determine divisibility rules by looking for a pattern in multiples of a number. They will then utilize divisibility rules to find factors thereby strengthening this ability. The students will practice their factoring skills through the Four in a Row game. This lesson could be an introduction to divisibility rules but not findng factors. |
| Fantastic Factors: | In this lesson, students will start out using manipulatives to create arrays which will be used to find factor pairs. Students will use a T-Chart to determine the factor pairs of numbers. Students will then use their T-Charts to determine if a number is prime or composite. |
| Hooray for arrays!: | Students will identify prime and composite numbers through arrays. The lesson begins with a fun situational story. |
| Abundant Numbers: | This lesson provides practice in learning factors of numbers. Students will play a factor game then participate in a thought-provoking task. It is helpful if students know what a prime number is, but it is not essential.
|
| Using Rectangles to Find Prime and Composite Numbers: | In this lesson, students will be using rectangles to find prime and composite numbers. Students will draw different rectangles for the area of a given set of numbers. They will determine the factor pairs for each number in the given set and use them to discover the meaning of prime and composite numbers.
|
| Factor That!: | This is a foundation lesson in which the students will visually see the relationship between factors and products. As a result of this hands-on lesson and guided discussion, they will learn to identify the factors of a given number. |
| Numbers Grow Here: | The students will use prior knowledge of the area formula to design a garden with a area. Students will compare gardens and note that rectangles with the same area could have different dimensions. |
| Factor Word Challenges: | Students will apply multiplication, division and factor knowledge to word problems. |
| Pattern Fun: | In this lesson, students will use manipulatives to build, extend, and describe increasing patterns from a rule. |
| Fun with Factors: | This is an introductory lesson addressing factors for number 1-20. Factoring will lead students to discover differences and similarities between prime and composite numbers. Students will also discuss five claims about factors, prime, and composite numbers and create support from examples and non-examples to determine whether these claims are valid or invalid. |
| Searching for the Primes: | Students will use a 100s chart to sort out the prime numbers under 100 using the Sieve of Eratosthenes method. |
| Looking for Patterns in a Sequence of Fractions: | Students generate and describe a numerical pattern using the multiplication and subtraction of fractions. |
| Prime Factorization - From Fingerprints to Factorprints: | This activity provides an introduction to composite numbers and prime numbers through factorization. |
| Area and Perimeter of Rectangles Investigations: | Students will determine the validity of the statement, "All rectangles with the same area will have the same perimeter" through two investigations. |
