To help students to
i) recall the formula of a given chemical compound
ii) identify the metallic and non-metallic radicals
iii) frame the formula by matching the cards appropriately
A chart displaying the names of the following chemical compounds (50), Aluminium oxide,
- 100 discarded visiting cards
On each pair of cards, the symbolic representation of the metallic and nonmetallic radical of the coumpound is written.
Instruction to teachers
- Shuffle all the cards and distribute 10 to each of the students.
- Stack the rest of them face down
- Display the chart containing the names of the chemical compounds
- Draw the attention of the students towards the chart and tell that the formula of any of these compounds can be arranged using the matching cards.
- Ask the students to match one metallic radical with one non-metallic radical (from the given set of 10 cards) to form a compound. If the match is made correctly, the pair is kept aside. If no set can be made from it, the player picks up one card from the pile to make a match . Here again if it does not help, the card is put back, face up.
- Once a student makes a pair, check whether the combination is correct.
- Ask the students to take turns to pick up cards to make the sets.
The student who make the maximum number of pairs is the winner.
