What children will practise

Matches four topics: animals to life cycles, states of matter to examples, forces to their effects, and organs to their jobs. Links to ว 1.2 ป.3/3, ว 2.2 ป.3/1 and ว 1.2 ป.1/1; the tagged code ว 1.1 ป.2/1 does not exist in the indicator list.

What's in the worksheet

4 questions, a matching game with four pairs each - Match a butterfly to egg, larva, pupa, adult, and a cat to kitten, adult cat - Match gas to water vapour and liquid to water - Match friction to the object slows down and a pull to the object moves closer - Match lungs to exchanges gases and brain to controls the body

How to use it in class

A cross-unit end-of-term review, about 6-8 minutes, since it combines four unrelated topics. Play in teams and rotate who taps each question. On question 2, warn children that soil is also a solid and the word ผสม (mixture) is the clue. For question 3, have children push and pull a chair. You can link it to a class and record it in the gradebook.

Common sticking points

- Question 2: matching solid to soil and mixture of solids to ice, since soil really is a solid. Accept that this item is ambiguous. - Question 1: swapping frog and chicken because both answers begin with egg. Look for the word tadpole. - Question 4: matching lungs to pumps blood because exchanges gases is hard for Grade 2. Rephrase it as breathing air in and out.
