PDF Lesson 5- Level 5-6- Factors and multiples- Presentation

Pdf Summary

The document is a series of instructional and problem-solving exercises focused on concepts of multiples, factors, and divisibility, designed for Math Kangaroo participants at levels 5-6. It includes vocabulary, mathematical concepts, and several problem examples that illustrate the application of these concepts in mathematical problem solving.<br /><br />**Key Concepts:**<br />1. **Factors**: Numbers that divide a given product evenly. The document explains how to find factors through examples, like the factors of 24.<br />   <br />2. **Prime Factors and Composite Numbers**: A prime number is divisible only by itself and 1, while composite numbers are factorable. Prime factorization is explained with examples.<br /><br />3. **Divisibility Rules**: The document outlines rules for determining if numbers are divisible by integers 2 through 10, providing shortcuts for quick calculations.<br /><br />**Problems Provided:**<br />- Determining factors not belonging to a given number.<br />- Calculating prime factors of 2000.<br />- Finding numbers divisible by specific integers.<br />- Identifying a certain number based on statements about its characteristics.<br />- Solving problems based on intervals at which different people visit a computer lab.<br />- Calculating the number of divisors of a given product.<br />- Discovering five-digit numbers with specific properties.<br />- Packing marbles to figure out the smallest number of boxes needed.<br />- Determining how many numbers on a blackboard are underlined exactly twice based on divisibility.<br /><br />The wrap-up section emphasizes the importance of understanding factors and primes in solving multiplicative and divisible problems. Additionally, the document suggests optional homework for further practice.<br /><br />This document is an educational tool aimed at enhancing the understanding of multiples, factors, and divisibility with practical problem-solving exercises in preparation for the Math Kangaroo competition.
