What We Have Learnt in Term 3 Week 7

Mathematics

1. Multiplication as repeated addition

4 + 4 + 4 = 3 groups of 4 = 3 fours = 3 x 4

Please note: Emphasize that we added '4' three times. Hence it is 3 x 4.

Common mistake: 4 + 4 + 4 = 4 x 4

2. Multiplication in word problems.

Please note:

a. Highlight the word 'each' and 'altogether'. This helps them to differentiate (tell the difference) between addition problem sums and multiplication problem sums.

b. Clarify that 'each' represents how much one 'group' i.e. bottle, basket, box has. Emphasise that it also means that each group has the same number of objects.

Example:
Missy had 3 bottles. Each bottle has 4 marbles. How many marbles are there altogether?

Correct answer: 4 + 4 + 4 = 12 or 3 x 4 = 12

Common mistake: 3 + 4 = 7

English

1. We revised singular and plural nouns. Pupils need to remember when to add 'es' and when not to.

Grammar rule for -o words:

Add 'es' when a consonant is followed by the letter 'o'.

Examples: tomato - tomatoes, potato - potatoes, hero - heroes

Add 's' when a vowel is followed by the letter 'o'
Examples: kangaroo - kangaroos, video - videos, radio - radios

Exceptions:

  1. Shortened words, where you add "-s". For example, "autos" ("automobile"), "photos" ("photograph"), "kilos" ("kilogram"), "Zoos" (zoological garden).
  2. Words with Italian origin. For example, "graffito" becomes "graffiti", and "inferno" becomes "infernos", zero becomes zeros.
Common mistakes: tomato - tomatos , onion - oniones, is - was
Correct answer: tomatoes, onions, are
