Magnificent Maths

Kia Ora and welcome back to my blog post 2021.  Today in week 6 term 2 we have been learning Tidy numbers and Place value.

       +1   -1

      49+67=116

      50+66=116

How you do Tidy numbers is you add one on the 49 then you minis 1 of the 67 which then makes the question 50 +66=116.

244+223=447

Then how you do place value is you don't add the 1 on 224 or minis 1 on 223 because that is tidy numbers not place value. Anyway let's get back to work on place values.  Okay what you do is 200+200=400 then 20+20=40 and last 4+3=7 then you go like this 400+40+7=447.

I hope I have made it sound easy to you to understand and what do you know about tidy numbers and place value.

Here is my slide show I hope you like it.
