Adding Mixed Numbers and Improper Fractions

By K5 Team

posted Jun 15 2017 - 2:29pm

Just like whole numbers, fractions can also be added. The difference is that when counting improper fractions and mixed numbers, we are now counting the number wholes and parts.

Let’s work through an example to demonstrate how we add mixed numbers and improper fractions.

The example is: add the fractions

$adding mixed numbers and improper fractions$

Step 1: Convert all mixed numbers into improper fraction.

Is it more/most or -er/-est?

tall, taller, tallest Is it correct to say “more pretty” or “prettier”. Are there some concrete rules to help students modify a noun?

There are, but as is the case with English, there are some exceptions to the rule.

Adjectives and adverbs describe nouns. So when we make comparisons we make a change to the adjective or adverb. For example:

That cat is prettier than my dog.
The bird sings louder than my sister.
You have to be more careful when crossing a busy road.

Let’s start with the rules for comparisons involving adjectives.

What are Run-on Sentences?

What exactly are run-on sentences? Why do we care about them?

Run-on sentences

Basically, run-on sentences are sentences that lack proper punctuation.

A run-on sentence is made up of at least two parts. Either one of these two parts (or clauses) can stand as a sentence by itself. Somehow, though, they have been connected and that can lead to some confusion by its reader.

Here’s an example of a run-on sentence:

We went to the beach it was fun to play in the sand.

Here’s the correction:

We went to the beach. It was fun to play in the sand.

Five Books That Inspire Kids to Write

By K5 Team

By Sheila Welch

For elementary students who are writing essays and fiction, these books might prove helpful as well as interesting for both children and parents.

Officer Buckle and Gloria

OFFICER BUCKLE AND GLORIA by Peggy Rathmann is the irresistible tale of a sweet-natured cop who writes safety tips that he reads to the indifferent students at Napville School. When he gets a police dog, he’s thrilled to have his assemblies and his tips suddenly become popular. This classic picture book will introduce children in first through third grades to the concept of writing notes as reminders. But it will be best remembered for its wonderful characters, humor, and clever plot.

Grade 3 Geometry Worksheets

We’ve had a gap in our grade 3 worksheets that we’ve now filled. We’ve just added grade 3 geometry worksheets to our grade 3 math worksheet section.

Topics included in this new geometry section include:

Basic properties of 2-D shapes: quadrilaterals, triangles, circles and polygons.

Lines and angles: reviewing the difference between lines, segments and rays, and learning to measure and classify angles.

Area and perimeter of 2D shapes. We wrote an blog piece on learning to calculate the area and perimeter of rectangles and squares a while back, in case you need a refresher.
Learning to identify congruent shapes.

Finding lines of symmetry and learning to draw symmetrical shapes.

Rounding Numbers

By K5 Team

posted May 1 2017 - 11:27am

Why is it important to learn to round numbers? This is a practical skill that your kids will take with them into their everyday lives, because rounding numbers help us calculate sums easier in our heads.

For example, you and your friends are buying pizza and you want to make sure you have enough money to buy four large pizzas with various toppings. Rounding the cost of each pizza to the nearest dollar and adding the amounts is a quick and easy way to make sure you have enough money to pay for them.

So, we round numbers because:

It makes it easier to describe and understand numbers.
It makes it easier to estimate answers to numeracy questions.

Learning About Punctuation

By K5 Team

posted Apr 20 2017 - 10:17am

Punctuation is to writing what vocal delivery is to speech. Every full stop, comma, apostrophe, colon, parenthesis, quotation mark and hyphen serves its purpose in guiding the reader through the text. It’s useful to know what each mark can and cannot do, as well as the message it delivers to your reader.

Here are some simple rules and examples.

Faces, Edges and Vertices of Shapes

We have just added some more geometry pages to our grade math 2 section of our free worksheet center.

Let’s take a look at one of the topics we cover in the grade 2 geometry worksheets: faces, edges and vertices of shapes. Exactly what are these and how do you count them for different shapes?

Vertex

A vertex is a corner. In 2-D shapes, that’s pretty easy to work out – a triangle has 3 vertices, a square 4 vertices and a pentagon 5 vertices.

In 3-D shapes it gets a little more complicated. Let’s look at a cube, for example. A cube looks like this:

Recognizing Common Number Patterns

By K5 Team

posted Apr 6 2017 - 11:23am

Is it important that our kids learn to recognize patterns and sequences in math? The answer is a resounding yes.

Exploring patterns and learning about math sequences help young students build important foundations for later number work. Simply put, with the early work on recognizing patterns, students gain an understanding of mathematical relationships, which is the basis for understanding algebra, analyzing data and solving complex mathematical problems.

Here are the most common patterns:

Arithmetic sequences

An arithmetic sequence adds or subtracts the same value each time.

For example:
1, 5, 9, 13, 17, 21…
