A little word at the front that flips the meaning

Lesson 4 of 17
Year 1

Task 1 gives the letter of the right option as printed on the sheet. Task 2 lists the mistakes in the order they appear, with the correction. Task 3 and 4 answers are models, not the only acceptable wording: any answer that uses the rule the lesson taught should be credited.

Mildun means not. re means again. The word inside never changes.

1 · Tick the right spelling

a Bb Ac Ad BA = left option, B = right option

3 · Now you write

Model answers
  1. The café door is unlocked.
  2. Polpetta will reheat the soup.
  3. I was unhappy. Unhappy means not happy.

4 · Help Polpetta

It is wrong because un means not, not again. Uncook would mean the opposite of cook. To heat it again he needs re: reheat the soup.

2 · Find the 3 mistakes

unlocked is the un word that is already right (the decoy).

Mediumun means not, or the opposite. re means again. The word inside never changes.

a Bb Ac Ad BA = left option, B = right option

3 · Now you write

Model answers
  1. Tick: unlock, untidy, unhappy · The kitchen was untidy after lunch.
  2. Tick: reheat, refill, retie · Polpetta will reheat the soup.
  3. The door was unlocked, so we could refill the jug.

4 · Help Polpetta

Un means not or the opposite, so uncook would mean the opposite of cooking. Again is re, so he should reheat the soup.

2 · Find the 4 mistakes

2uncookreheat

unlocked is the decoy. uncook is a meaning mistake (un for re), not a spelling one; accept reheat or warm up.

SpicyRead the meaning first. Then choose the front bit, and check the word inside.

1 · Tick the right spelling

a Ab Bc Bd AA = left option, B = right option

3 · Now you write

Model answers
  1. I had to unpack the whole box and repack it neatly.
  2. unhappy, and the word hiding inside it is happy.
  3. My uncle sat under the table. Uncle and under start with un but do not mean not.

4 · Help Polpetta

Un only goes on words that English already uses it with, like lock or happy; you cannot put it on any word you like, and unenter is not a word. He should write Please do not enter. A real un word is unlock, or unwelcome.

2 · Find the 6 mistakes

1unhapyunhappy
2uncookreheat
3unnkindunkind
4reeopenreopen
5rebiltrebuilt
6unsaffeunsafe

unnecessary is the word that looks wrong but is right (un + necessary). uncook is the mistake that is not a spelling mistake; accept reheat.
