70,899.384 - 70,898

70,898 is between 70,897 & 70,899. Since I am rounding up to the nearest whole number I will look at the tenths place whether to round up or down.Because 8 is greater than 5.I will round down to 70,898

• 2,469.491 - 2,469

2,469.491 is between 2,469 & 2,470. Since I will be rounding it to the nearest whole number I take a look at the first whole number in the ones place then look to the right which is the tenths place and since 4 is lower I will be rounding down. Which brings you 2,469

• 41,806.607 - 41,807

41,806.608 is between 41,806 & 41,807.

WALT - Round to the nearest ten

1. 2,469

2,469.491 is between 2,460 & 2,470. Since I will be rounding it to the nearest ten. I first take a look at the tens place then look to the right and change the 9 to 0. Now since 9 is higher than 5 I will be rounding up to 2,470

2. 41,8O6

41,806.608 is between 41,800 & 41,810. Since i am rounding it to the nearest ten I first take a look at the ten place and to decide if to round up or down and since 6 is higher than 5 I will be rounding up to 41,810

   4. 658,414

658,414.584 is between 658,410 & 658,420. Since I am rounding it to the nearest tens I first take a look at the tens place then look to the right which is the ones place and then change the 4 into 0. Now since 4 is lower than 5 I will round it to 658,410

  5. 3,605,435

3,605,435.85 is between 3,605,430 & 3,605,440. Since I am rounding it to the nearest tens I take a look at the ten place then look to the right which is the ones place and then change 5 into 0. Now since 5 is to 5 you still have to round down to 3,605,430.

Writing.

This morning, we were announced that Laura Tupou the news reporter from Newshub was going to be attending our school. When she was telling us about how much she loved books and reading she also mentioned that she worked for Radio NZ. Laura also spoke about how bad she wanted to do her older siblings homework and loved doing her brothers homework as well.

Dear Laura Tupou,

I commend your occupation and how you’ve motivated us with your speech. I thank you for making us students of Glen Innes School notice that reading is a good subject which can help us and lead our future to a good place. Thank you for visiting our school and telling us about your great journeys while working at Newshub. It must be great fun working there and getting to meet celebrities and getting to  spend time with them. Hope you have a great time spending time with Prince Harry and Princess Megan.
