Bonny and tommy take a look at the seasons

Educator section


This module still consists mostly of activities for consolidation, reinforcement and assessment of the work taught in the previous grades focusing on the number 100.

  • Number concept to 200.
  • Operations: - Consolidates all work covered in Grade 1 en 2.

The names of the months and the correct spelling thereof need to be attended to. Discussions about the seasons and a healthy environment (nature conservation) will provide opportunities for the integration with other learning areas.

Weather charts for the different seasons can be recorded e.g. February – summer; May – autumn; August – winter; November – spring. These are not the best months for the seasons but they are the months in which the learners attend school for the whole month. Complete a bar graph for every weather chart so that weather conditions can be compared and discussed. Having completed all the bar graphs these can be compared to one another and the learners can discover weather conditions relevant to their own regions as well as those relevant to each season. The educator can keep the graphs to compare the statistics with the next year’s graphs.

The tasks and activities in Learning Unit 2 are still mainly intended for consolidation of work covered in previous grades. It is essential, however, that educators continue to make use of concrete apparatus to repeat, explain and consolidate all concepts that were not fully mastered before.

It is of the utmost importance that learners must be totally familiar with the tens grouping of our numbers system:

10 ones are grouped as 1 group of ten

10 tens are grouped as 1 group of a hundred

10 groups of a hundred are grouped as 1 group of a thousand , etc.

Learners must work with counters that have been grouped in hundreds, tens and units . Should counters not be available, the following semi-concrete apparatus can be used.

The expansion cards (flared cards) are very useful in explaining place values, renaming, unifying of numbers and the 0 as place-keeper.

Attached you will find an example of expansion cards (flared cards) and a key to writing all number names. Flared cards enable learners to build any number, and if learners know the basic number names, they can construct and write any number name from the given parts. Give each learner a copy to use, for example


Number name: one thousand one hundred and thirty seven

If you wish to use this example, enlarge it and copy it on manilla.

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
