1st Class Ms. Barry

27th April – 1st May 2020

Happy Monday everybody 🙂 I hope you all had a lovely weekend.

I have sent all of this information in an e-mail from firstclass@scoilbarra.ie to all parents, along with another e-mail last Wednesday. If you have not received an e-mail from this address please send an e-mail to firstclass@scoilbarra.ie with Ms. Barry and your child’s name in the subject box.

This week’s maths is quite tricky (starting Wednesday). It is renaming – when your units add up to 10 or more they need to be renamed as tens and units. Please do not worry if your child is finding these difficult, this is all new to them, we have only been doing it in games and orally so far. They will be doing it from scratch once they return to school. I have attached a video explaining it to them. I will also write out a list of rules below which they will need to follow. They know the first four rules inside out at this stage.

I will also post photos of a game they can make themselves out of squared maths copy paper at home to help with renaming (they may need help with the cutting). All they will need is a dice which can also be made using paper and selotape if you don’t have one at home, and a blank sheet of paper with hundreds, tens and units written on it. This game is not essential, but most of them really enjoy it and it helps.

You will need to draw:

One 100 square

10 tens

15 units

(The reason for 15 units is in case there are 9 units in the units already and someone rolls a 6. 9 + 6 = 15 )

A banker chart.

The children know how to play this game but I have explained it in the video to avoid any confusion – you roll the dice and add on the amount of units, as soon as the units go to 10 or above the children should spot that they need to exchange / rename the units as tens and units. The person who rolls the last number that brings the total to 100 or above wins. Eg. If we have 9 tens and 8 units (98) and it’s my turn and I roll a 6. 8 units + 6 units = 14 units. I need to exchange / rename 14 to 1 ten and 4 units, when this is put with the other tens we now have 10 tens and 4 units (104), 10 tens need to be exchanged / renamed as 100, now we have 104.

These are our rules. The first four are for ALL sums.

  1. T + U
  2. Line down the middle
  3. Check the sign
  4. Units first (ALWAYS)
  5. 10 or more units? Draw a bubble
  6. T + U on the bubble
  7. put the u under units
  8. put the t to tens side
  9. add all then tens together
  10. ALWAYS check that you have used your t and u from the bubble – make sure you have moved them to the right place.

I have attached step by step photos on a collage.

Please do not hesitate to email me if you have any questions, I would be delighted to help.

Thank you again for all the amazing work that is being done at home.

Talk again soon Ms. Barry 🙂
