Numeracy: Problem Of The Week
Factors - Order of Operations - Variables
Factors - Order of Operations - Variables
Two different positive whole numbers, a and b, are both greater than 1. The second number, b, is larger than the 1st number. After the second number is increased by 1, it is multiplied by 1st number. The resulting product is 260. This information can be represented by the equation a x (b + 1) = 260.
Determine all possible pairs of numbers that satisfy the equation.
Work collaboratively in a group of 4 to solve the problem above. Show all your thinking on chart paper using a combination of diagrams, numbers, calucations, and/or words. Be prepared to share your problem-solving strategies.
Remember to:
- Understand the problem
- Think of a strategy
- Carry out the strategy
- Reflect on your approach
Well done to everyone that participated in our first math Skype with St. Maria Goretti's grade 7 class - great job! You all demonstrated excellent collaboration and communication skills. We look forward to engaging in another problem of the week very soon. We also thank our Principal, Mr. Boccia, for participating in this new experience.
Our solutions:
We solved the problem of the week using what we already knew about factor rainbows, order of operations, equations and using trial/error.
