Questions and Solutions

Question 1

There are 4 objects. Take away 2 objects. How many are left?

4 Take away 2 Left

Solution:

We start with a group of 4 objects. The problem asks us to 'take away' 2 objects from this group. Imagine you have 4 toys. If you give away 2 toys, you need to count how many toys are remaining with you.

Let's visualize this:

We have 4 objects: O O O O

We need to take away 2 objects: O O

After taking away 2 objects, we are left with: O O Counting the remaining objects, we have 2.

So, 4 take away 2 leaves 2.

Answer: 2

Question 2

There are 2 objects. Take away 2 objects. How many are left?

2 Take away 2 Left

Solution:

We begin with a collection of 2 objects. The instruction is to 'take away' 2 objects from this collection. This means we remove all the objects that are present.

Let's represent the objects:

We have 2 objects: O O

We need to take away 2 objects: O O

When we take away 2 objects from the 2 that were there, there are no objects left. O O Take away O O Left: (None)

Counting the remaining objects, we find there are 0.

Therefore, 2 take away 2 leaves 0.

Answer: 0

Question 3

There are 3 objects. Take away 1 object. How many are left?

3 Take away 1 Left

Solution:

We start with 3 objects. The task is to 'take away' 1 object from these 3. This means we remove one item from the group and then count what remains.

Let's visualize the objects:

We have 3 objects: O O O

We need to take away 1 object: O

After removing 1 object, the remaining objects are: O O By counting the remaining objects, we find there are 2.

So, 3 take away 1 leaves 2.

Answer: 2

Common mistakes

  • Confusing subtraction with addition.
  • Incorrectly counting the remaining objects.
  • Difficulty in understanding the 'take away' concept visually.

Revision tips
