Block 1: Past Tens

Welcome to the ‘learning game’. Just like any other game, this game has rules and goals. The goal of the ‘Math’ learning game is to become the ‘Master’ of math. Before you achieve that, you first need to master the simple art of counting. You will get points for different actions during this course. Get 150 points, and you will get a ‘Count’ badge. This is the first step to mastering math!

Today, we are going to experience and learn something very simple – we are going to learn about counting.
Imagine that you are one of the early humans. You were hunters, now you gather and farm.
You settle down and form a family. You plant crops and raise sheep.

Why do you need to count?

You need to keep a count of sheep, to make sure they don’t run off, or give birth to young ones without you knowing. The same applies to all the other things you own.

You have only one way of counting – you use your fingers. Now, you have figured out a way to store the number.
Look at Card 1 in your deck. You have a table. For each sheep you add a black token (black square means black token).

Card 1

Can you explain how you are recording the number of sheep?

Each sheep is shown by placing a black token on a tile.

Soon, you figure out a system to make keeping count of your sheep easier.
You decide that if one black token is there, you will call it “one’. If you have To use two black tokens, instead of “one black token and one black token, you call it two.
This way, you figure out all the way until the number of fingers you have, which is 10.
One grey block represents one sheep, so the total is represented below as seven sheep in figure 1.

A new family travels to your area. They have the same number of sheep as you. As a welcome gift, you give them a young sheep and another young sheep.

Can you help the new family to record how many sheep they have? Use Card 2.

Card 2

Expected Output

Place 7 tokens and two more tokens to get the total number of sheep

In Card 1, it is mentioned that 1 black token is 1 sheep. Write the same in this card after placing the token on the top left box.

Hold a copy of Card 1 and point out to the top row.

You know the numbers from one to ten. How many sheep does the new family have?

Nine sheep

To help your two families, you start working together for farming, hunting etc. You need to count all the sheep in your village. Can you record it in Card 2?

Expected Output

Place 7 tokens and then 9 tokens to get the total number of village sheep.

Congrats! You have started the first ever village!

A new traveler comes to your village. He has figured out a better way to count big numbers!
You will now use this ‘better’ way to count the total sheep in your village.
Give me a thumbs up after you complete each step.
Place Card 4 below card 3. Place Card 5 to the left of Card 4.

Expected Output

The first rule of this new system is that you should use 1 white token instead of 10 black ones.
Count 10 tokens from Card 3 and remove them.
Place one white token in Card 4. This is equal to 10 black tokens.

How many black tokens are left in Card 3?

Six tokens

Place them on Card 4.

Expected Student Output

What does one white token mean? How many sheep does this show?
10 black tokens so 10 sheep.
How many black tokens are there? How many sheep does this show?
6 black tokens.
Write one ten and six ones below each card.
The traveler tells you that the name for this number is sixteen.
