In preparing to learn how to properly key a calculator, 5th grade students must make sure they have an understanding of certain math concepts. Those concepts include understanding and basic algorithms of; place value, estimation and rounding, addition, subtraction, multiplication, division, and word problem key words.
Big Ideas: Decimal place value is an extension of whole number place value. This standard calls for students to reason about the magnitude of numbers. Students work with the idea that the tens place is ten times as much as the ones place, and the ones place is 1/10th the size of the tens place.
Rounding. Oh my....there will be so many times when rounding numbers (including decimals) will be a required skill. Let's get this down, shall we?
How can identifying key words help students solve mathematical word problems? In this lesson, students will take turns acting as "math coaches" who will assist other students in solving word problems by identifying key words that usually indicate specific mathematical operations.
Introduction to addition. Multiple visual ways to represent addition.
Introduction to subtraction
How to set up and work multi-digit multiplication problems using the standard algorithm.
Setting up and working multiplying multiple-digit numbers with each other using standard algorithm.
Dividing into larger numbers. Introduction to long division without remainders. Further down the list is an introduction on what to do with those that have remainders.
How to work with word problems that require multiple steps in order to come to an answer. This video deals with multiplication and division word problems.
In this lesson you will learn how to check your answer to a multiplication problem by using estimation.
