Adding Objects
Addition becomes easier when we can see and touch the things we are adding.
We can use objects such as pencils, blocks, buttons, fruits or toys to make two groups and then put them together.
Learning Objectives
- Add two groups of objects.
- Count objects correctly after combining groups.
- Connect objects with addition numbers.
- Write simple addition sentences.
Putting Objects Together
Suppose we have 2 blocks in one group and 3 blocks in another group.
After putting the two groups together, there are 5 blocks.
Count the Total
After combining objects, count all the objects to find the total.
Count all the objects:
Using Different Objects
Addition works the same way with different objects.
Apples
Pencils
From Objects to Numbers
Once we understand the objects, we can represent the same addition using numbers.
The objects show what is happening, while the numbers give us a shorter way to write the same idea.
Adding Three Objects or More Groups
We can also combine more than two groups when we are ready.
All three groups together contain 5 objects.
Common Mistakes
- Forgetting to count every object.
- Counting one object more than once.
- Leaving out objects from one of the groups.
- Writing the wrong total after counting.
Practice
1. Add 2 objects and 2 objects.
2. Add 3 objects and 4 objects.
3. Add 5 objects and 2 objects.
4. Write an addition sentence for 4 pencils and 3 pencils.
5. Find the total of 2 apples and 5 apples.
Try It Yourself
Collect two groups of small objects around you. Count each group, put them together and count the total.
Quick Revision
- Objects can help us understand addition.
- Put the groups together.
- Count all the objects.
- Write the addition sentence.
- The final count gives the total.
