Addition

Our latest Maths unit is focusing exploring ways to solve simple addition problems using a range of efficient mental and written strategies.  We are investigating using known facts, ten facts, counting on, using materials (like MAB) and how the order of the addends doesn’t change the total.

Teach someone at home how to play “Flipper” – you need a deck of cards with the kings, queens & jacks removed.

You could also explain to mum or dad what we did with the yellow pages.  I wonder what your phone number is worth.  The digits in mine add up to 32.

Here are some fun websites to help us practice increasing our adding speed and recognising addition facts:

Explanations – Why are some choices healthy?

We have been learning about some healthy choices we can be making to live well, play well and learn well.  We have been using our reading skills to do some research and then our writing skills to record explanations.  An explanation text explains why, how or what?  So far we have written explanations about why it is important to get plenty of sleep and why it is important to drink water.

I wonder who can explain some of the reasons we have found about why it so important for us to sleep and drink water?

 

Mastermind – using a place value chart

One of our goals this term was to understand numbers better.  One strategy to help us achieve this goal was to start using place value charts to think about the digits that make up a number.  We have been practicing how a digit can hold a different value.  For example the 8 digit can be 800 in 846 or 80 in 387 or 8 in 238.  We have also been exploring different ways to think about a number – in words, modelling with base ten blocks (MAB) and extended form.  Another challenge has been to think about 10 more & 10 less and 100 more & 100 less.  It would be good to keep practicing some of these skills at home.

You could print out this activity page:  NumberoftheDay copy  We would love to see some filled in!

This week we have learned the game “Mastermind.”  This game helps us use a place value chart.  You can play this game at home.  Here are the instructions…

It has been a lot of fun learning more about how numbers work 🙂

Learning About Recounts

Over the last few weeks we have been making sure we know how to write recounts.  A recount tells the audience about things that have happened, are a way to record past experiences and you need to make sure you include events in the order they happened.  When you write a recount you have to use verbs in the PAST TENSE and include lots of TIME CONNECTIVES.

Mrs McMahon took 2M on an amazing race around different parts of the school.  There were challenges that needed to be completed and the stop watch was on.  After we did the race, we had to write an interesting RECOUNT about it.

Here’s what we looked like on the race…

Understanding more about numbers

This week to help us reach our numeracy goal (to understand more about numbers) we made ourselves a set of ARROW CARDS.  These place value cards are sometimes called Montessori cards.  They help us to understand that a number is made of digits that hold different values.  They also help us understand that 0 holds a value too.  This is really important!

  

You can make a set of Montessori cards at home if you like.  This template will help you understand 1, 2 and 3-digit numbers. Remember make the ones, tens and hundreds each a different colour (e.g. 2, 30, 500)

Or you could make yourself another set of arrow cards (the arrows help to make sure you overlap the digits correctly)

Or if you are really lucky and have a colour printer you could make yourself a fancy set of arrow cards

I wonder if you can teach mum or dad to use ARROW CARDS to make 2-digit numbers, 3-digit numbers or 4-digit numbers?
