Meet Duo the Number Star and learn the addition table of 2. We will read the table, watch each sum appear, practise in order, practise in mixed order, and then win a certificate.
Look at the whole table first. This is our map.
Big idea: the first number stays 2, and the answer gets bigger each time.
So if we see 2 + 4, we add 2 more. The answer is 6.
Read each row slowly. Point with your finger if that helps. We want your eyes, ears, and brain to work together.
Read each line: 2 plus something equals the total.
We will show each sum one part at a time.
On this page, the sum appears like this:
2 → + → 1 → = → 3
After the answer appears, read the whole sentence aloud:
Two plus one equals 3.
Start with 2 + 1 and go all the way to 2 + 10.
Now it is your turn.
Each question gives you 3 choices. Pick the correct answer, then move to the next one.
Because these are in order, you can notice the pattern: the answers keep growing as the second number grows.
Now the sums jump around. Let’s see if you still know them.
This time, the questions are not in order.
You might see 2 + 4, then 2 + 7, then 2 + 2.
That is how we check if you really know the table, not just the order.
Let’s lock the pattern into your memory.
Here is the whole trick in one sentence:
When you add 2, the total gets 2 bigger.
If the second number is 8, then 2 + 8 = 10.
If the second number is 10, then 2 + 10 = 12.
= 4
= 7
= 9
= 12
Listen to your animal coach before you begin.
Olly the Owl has one last question for you.
Do you feel confident? Can you say the table of 2 by heart?
If yes, press the thumbs up button and move on to the final quiz.
If not, that is okay. Go back, practise more and more, and then come back when you feel ready.
