Finding the total number of something when you are given the fractional part can be tough for students. Most students are taught how to solve this by working backwards, but using a bar model might actually be easier for kids who have not worked through these problems before.

The bar model shows them visually how we work backwards to get to the total.

Here’s an example:

Samantha bought a pair of shoes for $36, which was 2/3 of her money. How much money did she have initially?

In this problem we know the part is $36, but we don’t know the total. Divide the total into three parts and mark the two parts that are $36.

About 60% of English words contain silent letters. So it’s important for our kids to learn how to spot them.

There are some rules that will help explain which letters are silent, but as with all English rules – there are always exceptions to the rule.

## Silent A Words

Rule: A is not pronounced in many adverbs, where the words ends in –ally. For example: stoically, logically.

Here's a list of common silent A words:

Knowing mental math tricks is a critical skill in math. Knowing how to do this you will be able to work out sums in your head more rapidly . Here are examples of some mental math strategies for subtraction.

## Compatible Number Estimation

We use compatible numbers to estimate the answer. To use this estimation strategy, change the actual numbers to compatible numbers. For example:

Most children go through a phase where they treat irregular verbs like they are regular. They notice the larger pattern and apply it to all verbs: in the past tense words attach an –ed at the end. When they notice this pattern, they start making these over-regularization errors.

“I putted my toys away.”

“My brother eated the cake.”

“I teached grandma to use the iPad.”

With mental math tricks you will be able to work out sums in your head more rapidly – a critical skill in math. Here are examples of some mental math strategies for addition.

## Break Up the Numbers Strategy

This strategy is used when regrouping is required. One of the addends is broken up into its expanded form and added in parts to the other addend. For example:

can be calculated this way:

What are pronouns? Why do we use them?

Pronouns take the place of a noun and we use them so that we don’t have to repeat a noun. This helps to simplify speech and writing by using a word to represent longer passages and ideas.

For example:

Frank and his buddy Tim went to the beach on their day off.

Instead of:

Frank and his buddy Tim went to the beach on Frank and Tim’s day off.

Long multiplication is intimidating, especially when you multiply large numbers. Here are two easy ways to do long multiplication.

## Method 1: the shortcut method

Let’s say you are multiplying 425 by 15.

Write down one number next to the other.

Split the smaller number into tens and ones. In this case that would be 10 and 5.

Sight words account for up to 75% of the words used in early reading materials. Many of these words do not follow the basic phonics principles - they cannot be ‘sounded out’. Therefore, it’s important that kids from an early age learn these words by sight.

Learning the Dolch List of Basic Sight Words and Fry’s Instant Sight Words using Flash cards and worksheets becomes tedious quite fast – especially for young kids. How about trying one of these games instead?

## Wordo

This game is played like Bingo, but instead of numbers you will be using sight words. You’ll need to make some bingo cards. Go to our sight words flash cards pages:

Or

Pick the grade or selection of words you’d like to practice. Print out each set. Then cut along the straight lines. Get a piece of paper and glue on the selection of words in a grid on the paper. You’ll need to print out the set several times for enough Wordo cards to go around.

## What is long division?

Long division is a way to solve division problems with large numbers. Basically, these are division problems you cannot do in your head.

## Getting started

One of the problems students have with long division problems is remembering all the steps. Here’s a trick to mastering long division. Use the acronym DMSB, which stands for:

D = Divide

M = Multiply

S = Subtract

B = Bring down

This sequence of letters can be hard to remember, so think of the acronym in the context of a family:

Dad, Mother, Sister, Brother.

Students can confuse contractions and possessive nouns because they appear similar because of the apostrophe. However, they are quite distinct.

## What are Contractions?

The word contraction means “the process of becoming smaller”, just like when you let the air out of a balloon or exhale from your lungs.

In grammatical terms, when we speak of contractions it means a shortening of words. A contraction is a shortened form of two words written as one word and an apostrophe takes the place of the missing letter or letters. This includes common contractions, such as I am shortened to I’m or odd contractions, such as of the clock shortened to o’clock.

Here are lists of common contractions:
