Did you know there are several ways in which you can solve 2-digit addition? Here are four of the most common ways students learn to solve 2-digit (and for that matter 3-digit) addition problems.

We’ll use 89 + 34  as our 2-digit addition example.

Break Apart

Here the student breaks apart the addition problems using place value.

89 breaks into 8 tens and 9 ones, 34 into 3 tens and 4 ones.

cannot can't can notCannot, can not and can’t are so similar, so does it matter which one you choose? There are differences, so it's important to know when to use each.


Cannot is a contraction of the two words can and not. It describes an action as impossible or not allowed. Cannot is most commonly used in formal writing.

For example:

I cannot come out to play until I have finished dinner.
You cannot possibly jump that far.

When describing an action which is impossible, you should always use cannot.

grade-1-measurement-worksheetIn addition to our grade 4 and 5 measurement worksheets, we have now completed the measurement worksheets for the lower grades: 1, 2 and 3.

Grade 1 Measurement Worksheets

The grade 1 measurement worksheets focus on the concepts related to measurement of length – longer/shorter, and the ordering of objects by length. We also introduce the measuring of lengths in non-standard units, and customary and metric units are introduced.

Grade 2 Measurement Worksheets

In the grade 2 measurement worksheets we progress from the concepts related to the measurement of length, as we as start with weight, capacity and temperature. Both the customary and metric systems are covered in these worksheets.

Grade 3 Measurement Worksheets

In the grade 3 measurement worksheets, we progress the understanding of the measurements of length, weight, capacity and temperature and introduce these in real-world situations. We also provide practice in converting between customary and metric units.

As you may already know data is a set of values based on facts, figures or other pieces of information that we use to learn about something.

For example, the number of dogs per family in a town.

That data can be presented in different ways. Data can be measured (such as length or weight) or numerical (basically numbers). We call these continuous data and discrete data.


Continuous data

Continuous data is measured. Continuous data can take on any value as it’s measured.

timerFor example:

Your weight. Your weight can be any weight within the range of human weights. Your weight is not a specific fixed number.

Time in a race. A race can be timed to a millisecond. Again it’s not set to a specific fixed number.

Isn’t a number just a number? No, numbers are quite diverse and can be classified in several ways. Cardinal, ordinal and nominal numbers are common number types that we see in our daily lives – but which is which?

Cardinal numberscardinal number

Cardinal numbers, also known as the ‘counting numbers’, represent a quantity in reality.

For example, when you state your age, read a price or count the number of cows in a field.
