Elementary Mathematics

Decimal notes that cover adding, subtracting, multiplying, and dividing decimals.

This video describes math in other bases using base 4 and base 2. It explains why and how math is different when using different bases. It explains base 10.

This video is an introduction to place value (tens and hundreds). Place is the place of a digit within a number. Value is how much a digit is worth.A digit is a single numerical symbol, a number is one or more digits together.

Class notes modeling addition and subtraction strategies using base 10 blocks, expanded form, traditional algorithm, and number line.

Splitting numbers based on place value such as ones, tens, hundreds, thousands, and so on.

Using a number line to plot a point and counting towards the right for addition and the left for subtraction.

Manipulatives in ones, tens, and hundreds that help students learn addition and subtraction.

Fraction notes that cover multiplying and dividing fractions.

Week 8 was Exam 1 - the exam covered topics from weeks 1 through 7

Fraction notes showing examples of adding, subtracting, multiplying, and dividing fractions.

Division notes with examples of division using array, equal groups, number line, repeated subtraction, strip diagram, and fact families.

A prime number is a number that is only divisible by itself and 1. A composite number has more than 2 factors. Factoring is to express a whole number as a product of other whole names, for example: we can factor 12 as 3x4 or 2x6 - both are whole numbers that multiply to make another whole number.

We discussed multiplication strategies such as arrays, equal groups, number lines, repeated addition, skip counting, area models, lattice method, partial products, and traditional algorithm.
