2) Assessment
3) Project idea: Divisibility test of numbers from 1 to 10 in base 10An enrichment project.
Grade Level: 10-12
Purpose: The students will gain better understanding of the divisibility of numbers in base 10 and the students will be challenged to think mathematically.
Description of activities: The students will first make conjectures about the divisibility for each of the numbers from 1 to 10. Then they will need to reason to themselves about why or why not the conjectures work.
Sources: N/A
Length of time project will take (in and out of class): 2 classes, 2 weeks
What students are required to produce: A poster or pamphlet of the students’ own conjectures on the divisibility test of numbers from 1 to 10 in base 10.
Handouts, graphics, etc.: N/A
Marking criteria: Number of solutions; Organization; Appropriate conjecture (i.e. not just saying to plug the numbers into the calculator…)
