Two-step word problems can be difficult to solve as the student needs to work out what should be solved first and then determining and solving both steps. Most two-step word problems that involve multiplication have a multiplication step and an addition or subtraction step.

The easiest way to solve these problems is visually with bar charts to aid the student.

Let’s start with an example that involved a multiplication step and a subtraction step.

In this example, the multiplication step comes first and the subtraction step second.

A girl has 7 lollipops and she has 5 times as many candies. How many more candies than lollipops does she have?

## Summer learning

The human brain is like a muscle – it needs regular exercise to stay in shape. So when those lazy summer days come around, we need to make sure our kids don’t forget what they have learned over the last 10 months of school.

Knowing what preposition to use can be hard, especially when they come in confusing pairs, where kids easily exchange them for each other. Here are some of the most common preposition pairs that confuse kids:

among / between

around / about

beside / besides

from / of

in / into

like / as

on / onto

Here’s a quick review of each pair and some example sentences.

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.
