Educator section


Critical and developmental outcomes:

The learners must be able to:

1. identify and solve problems and make decisions using critical and creative thinking;

2. work effectively with others as members of a team, group, organisation and community;

3. organise and manage themselves and their activities responsibly and effectively;

4. collect, analyse, organise and critically evaluate information;

5. communicate effectively using visual, symbolic and/or language skills in various modes;

6. use science and technology effectively and critically, showing responsibility towards the environment and the health of others;

6. demonstrate an understanding of the world as a set of related systems by recognising that problem-solving contexts do not exist in isolation;

7. reflect on and explore a variety of strategies to learn more effectively;

8. participate as responsible citizens in the life of local, national, and global communities;

9. be culturally and aesthetically sensitive across a range of social contexts;

10. explore education and career opportunities; and

develop entrepreneurial opportunities.

  • Integration of Themes: Friends
  • Social Justice: Friends should spend time together, e.g. playing games. Discuss in small groups what your attitude towards your friends should be when you play together.
  • A healthy environment: Why is sport important? Discuss the safety precautions needed when participating in sport at school.
  • Inclusively: Who should be allowed to participate in sport at school? Only team players? Or should the school accommodate everyone? Make you own graph of which learners participate in sport.
  • Number concept is extended to 50.
  • Counting in 2’s, 3’s, 4’s, 5’s and 10’s.
  • Calendar activities enable learners to order the months and revise ordinals.
  • Graph – a weather graph can be completed.
  • Bonds of 10 are introduced with many opportunities to reinforce these.
  • Measurement activities involving comparisons of height, length, width using related vocabulary.
  • Capacity – litre;
  • Identifying coins and shapes are included.

Activity: mass, doubling, halving [lo 1.1, lo 1.3, lo 1.9, lo 1.10, lo 2.2, lo 4.6]

  • Work in four groups:

You need: a wooden block, a large stone, a shoe, a book and a lunch box.

Group 1:

Compare the mass of the 5 objects by estimating.

Arrange them from the lightest to the heaviest.

Group 2:

Compare their mass. Use a balance scale.

Arrange them from the lightest to the heaviest.

Group 3:

Compare their mass by estimating.

Arrange them from the heaviest to the lightest.

Group 4:

Compare their mass. Use a balance scale.

Arrange them from the heaviest to the lightest.

LO 4.6
  • Think of three different ways to double 6.
  • I decided _____ was the best way.
  • Double 7 in three different ways:
  • Double 8 in any way.
  • Double 9 in any way.
  • Double these numbers:

4 ____ ; 7 ____ ; 9 ____ ; 8 ____ ; 6 ____

LO 1.10

“ flip the coin ”

1 5
  • Fill in the missing numbers on the block.

- Count to 20 and back to 0.

- Count to 30 and back to 0.

- Count to 40 and back to 0.

- Count to 50 and back to 0.

  • Choose a friend. Take turns to flip the coin on the block. Read the number it lands on.
  • Complete these patterns. The number block will help you.

what are the products of Nano chemistry?
Maira Reply
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
yes that's correct
I think
Nasa has use it in the 60's, copper as water purification in the moon travel.
