# Focus on Addition Combinations till 18

**Course Objectives:**

The course is basically designed to teach various concrete, pictorial and abstract concepts of addition till 18. The course is aligned to **US Common Core, Singapore Math Curriculum** and students will be introduced many new concepts like Number Bonds, Bar Modelling and will learn numerous strategies for fast addition combinations till 18.

The course has 12 modules. Each Module has a Lecture PPT *( Very Exhaustive Designed by Team of IITians and IIM alumuns ).* Unlike the traditional presentations, these presentations are blended presentations with videos and assessments blended in them. Students are requested to complete all parts of the Lecture for holistic learning.

Students can also play various games and also practice easy and difficult questions on the platform

### Project Work

**Number Bonds using 5 **

* 5's complement is something interesting , 1 + 4 =5, 2 + 3 = 5. We can tell small friend of 5 as *

*Small Friend of 1 = 4*
*Small Friend of 4 = 1*
*Small Friend of 2 = 3*
*Small Friend of 3 = 2*

*Now using this can be find the number bonds of 5. Write very fast in your Note Books*

**Activity - 2**

* Use Cube Blocks or Draw them and model the subtraction facts. Take a block of 6 and take one unit at a time and write down all subtraction facts from this*
* Use Cube Blocks or Draw them and model the subtraction facts. Take a block of 7 and take one unit at a time and write down all subtraction facts from this*

**Activity - 3**

- Use Cube Blocks and model Bar Model for two different sets of cube blocks. For example, 2 red and 3 green cube blocks can be written as a Bar Model as

Similarly students can write various Bar Models for atleast five decompositions

### Which of the picture fact represents 8 + 5 =13?

### Which of the picture fact represents 5 +4 =9?

### Which of the picture fact represents 6 +4 =10?

### Which of the picture fact represents 4 + 2 =6?

### Which of the picture fact represents 6-2 =4?

### Which of the picture fact represents 10-2 =8?
