Mailbox Maths

We have a special maths mailbox in our class now. Twice a week a letter appears in our mailbox and it always seems to be from a character that we have got to know through our stories Mrs Head reads. The character writes us a letter with a maths question they are having trouble solving. We try our best to work it out and then we write a quick letter back to reply to the character. Sometimes we use our oral language time to talk about possible answers and the strategies we have used to get to these answers other times the letter is read out and stuck on the whiteboard for us to go up and show our working on before writing the letter.
This helps us with reading (reading the letter), maths working with word problems understanding if we have to use plus, take-away, times or divided by and explaining our strategy. It also helps with our writing when we have to follow the structure of a letter to write back to the character.
Take a look at some of the examples of our recent mailbox maths.





Dear Your Majesty The Queen,
We have worked out your problem that you were having trouble solving.
First we started with the two minutes and added that with the three minutes that equals five minutes.
Then five minutes plus five minutes equals 10 minutes.
Then 10 minutes plus 10 from the 12 gives us 20 minutes then we added on the two from the 12 to give us 22 minutes.
Next we added 22minutes plus 6 minutes equals 28 minutes.
Lastly we got the two lots of 30 seconds which added together makes 1 minutes. So 28 plus 1 equals 29 minutes.
This means you listened to speeches for 29 minutes.
Yours Sincerely
 Room 11 and Mrs Head.
