Bonny and tommy’s school féte

Educator section

Memorandum

It is imperative that the educator is familiar with the content of this module before it is given to the learners, as this module contains advanced and enrichment work. Learners in the first two groups should find it a challenge and should be able to cope with it. Do not expose learners to tasks that are too difficult for them and which frustrate them. (Select according to their abilities).

The activities, the construction of mobiles, can be done classically. They can be combined with Technology.

  • Number Concept to 1 500
  • Operations :
  • Addition, subtraction and multiplication – two and three digit numbers with and without regrouping of the tens and the hundreds;
  • Division – two digit numbers with regrouping of the tens and remainders, e.g. 66 ÷ 4 =

In Module 7 number concept is extended to 1500. All addition, subtraction and multiplication calculations are performed with 2-digit and 3-digit numbers with and without regrouping of hundreds and tens. Division is only done with 2-digit numbers with regrouping of tens, with a remainder e.g. 66 ÷ 4 =

A discussion about the féte is necessary beforehand so that the learners may order their thoughts and plan the picture.

The learners must understand counting onwards from one thousand very well. Use similar number blocks from 1 101 to 1200, 1201 to 1300, 1301 to 1400 and 1401 to 1500 if necessary.

Shopping games should be used to help learners to calculate change.

Give special attention to equal quantities of and mℓ.

Use the posters for more calculations and provide opportunities for the learners to ask one another to do certain calculations.

This is an activity to be done on the playground. Let the learners measure with a trundle wheel.

Learners are expected to be able to count in a language other than their home language. If there are learners in the class who are proficient in another language, they should be given the opportunity to do so.

These involve consolidation of operations. Attend to problem areas.

The calculations of fractions of numbers may cause problems for some learners. Encourage them to try, even if they only accomplish the easier ones.

The 8x and ÷ are done simultaneously with eights . It is not compulsory for them to know these.

Multiplication is done with regrouping of hundreds as well as tens.

This activity tests the learners’ knowledge of numbers and reasoning abilities.

Division with regrouping the tens and a remainder requires much practice in the concrete. Learners must be able to say how they think and what they are doing before they attempt written work. Much practice is needed.

Encourage learners to test their operations.

This activity cannot be completed in one day. It can be combined with Technology. If there is not enough time, learners can be divided into groups of 5 to allow each learner to complete 1 shape, in which case the group will make a collective mobile sharing all knowledge with one another. If they find folding and pasting the round edges of the cone and cylinder they can paste these on the outside or they can cut off the round edges.

The shapes should preferably be duplicated on manilla, but if this is not available, use ordinary paper.

Content

Activity: make your own collective mobile [lo 3.1, lo 3.2]

  • These 3-D shapes have been cut open. Do you recognise them? They have been enlarged on the next pages. Follow the instructions and make your own mobile for your room.
  • Complete one shape at a time.

Instructions for all 5 shapes:

  1. Write your name lightly on all the shapes .
  2. Cut out 1 of the shapes neatly along the outlines (black lines) .
  3. Punch holes where it is marked with a o .
  4. Decorate the outside of the shape with your own patterns.
  5. Fold along all the dotted lines .
  6. Mark the grey sections . These must be folded over so that they can be pasted down.

Practise the folding over before you glue them.

  1. Apply glue onto one grey section at a time and paste it.
  2. Complete the shape and leave it for the glue to dry.
  3. Follow the same steps until all the shapes have been completed.
  4. Match the 3-Dshapes to the 2-Dshapes on p. 23 and write their names.
  5. Tie a piece of thin fishing-line to every shape .

12. Tie the shapes to a small plank and there hangs your mobile!

Assessement

Learning Outcome 3: The learner will be able to describe and represent characteristics and relationships between two-dimensional shapes and three-dimensional objects in a variety of orientations and positions.

Assessment Standard 3.1: We know this when the learner recognises, identifies and names two-dimensional shapes and three-dimensional objects in the environment and in pictures;

Assessment Standard 3.2: We know this when the learner describes, sorts and compares two-dimensional shapes and three-dimensional objects in pictures and the environment.

Select inflation type, Demand pull, cost pull or anticipation 1- Select the set of data you intend on graphing i.e inflation rate of 2017, location (particular country) 2 - Select the type of measurement tool that best allows you to input the inflation data, Consumer price index is the most accurate

what is difference between perfect and non perfect market.
Saheed
what the difference between Trade off and Opportunity Cost?
Elzevery
answer
Golda
In trade off, you increase the amount of something by decreasing the amount of something else. For example, you use 2 hours to study and 2 hours for leisure. if you increase study hour by 1 more hour, i.e 3 hours, leisure time will decrease by 1 hour, i.e 1 hour.
harmony
In all, you would have traded off 1 hour of leisure time for 3 hours of study time. But in opportunity cost, you let something go in order to obtain something else entirely.
harmony
thanks for your idea

the difference of it is that when demand simply denotes the willingness and a person's ability to purchase. And as against quantity demand represent the amount of an economic good or services desire by a consumer at a fixed price .☺
