Factor Fiesta with Mathigon

Slide 3

Introduce the learners to the ground rules. You can check out the Eddy Approach if this is your first time conducting an Eddy lesson. 

Slide 4

Let the learners know that they will be engaging in an imaginary pizza party to build excitement. Introduce them to the situation as depicted on the slide. Encourage them to write the equations in their respective notebooks. 

Slide 5

Once they are done writing the equations, show them the possible ways of dividing the pizza slices into equal groups. Ask them about the number of equations they could write.  

Slide 6

Introduce the concept of factors using the same situation of a pizza party. Use more examples if needed, such as a pizza with 4 or 6 slices. Write the possible equations on the board and reinstate the definition of factors. 

Slide 7

Let them imagine another pizza party where they have 7 slices of pizza as their dog or cat snuck one of the slices. Ask them if they can divide the 7 slices of pizza among 4 of their friends in a manner that each friend gets an equal number of slices. When they are not able to do it, ask why. Expected response - 7 cannot be divided by 4.

Slide 8

Let them know that they were unable to divide 7 slices into equal groups because it is a prime number. A prime number is any number that has only 2 factors (1 and itself). If one tries to divide a prime number by any other numbers, there will always be a remainder or a leftover slice. Give more examples of prime numbers, such as 2, 3, 5. Let them know that the opposite of prime numbers is composite numbers (numbers that have more than two factors), give them more examples of composite numbers if needed. 

Slide 9

Let the learners know that they will be doing an activity called ‘Factor Fiesta’ using Mathigon  where they will be finding factors for numbers ranging from 1-50 and they will use virtual manipulatives. 

Slide 10

Introduce the learners to the rules as mentioned in the deck. To understand and guide your learners on how to use Mathigon, refer to this tutorial.

Slide 11, 12

Introduce them to their roles within the team. If this is your first time conducting an Eddy lesson and want more clarity on the roles, check out the Eddy Approach.  

Slide 13, 14

Provide them with an example of how to split the number to find its factors as shown in the deck. Demonstrate one or two examples on the Polypad before the learners begin the activity. You can refer to the tutorial  to understand how to use, share, and assign a PolyPad. 

Slide 15

Once the learners are done identifying and noting the factors for all the numbers up to 50, ask them to reflect on the activity. You can use the prompts mentioned in the slide. Encourage them to think about how many numbers have common factors. 

Slide 16

Let the learners know that they would be engaging in an activity called ‘Prime Detectives’ to recap what they learnt about factors and prime numbers. Read out the instructions for the learners as mentioned on the slide. Once you ensure that the learners understand the instructions, start the activity.
