Te Rōpū Tapatoru

Today Miss Osborn was so impressed with the Tapatoru group. They were learning to solve multiplication problems using repeated addition. We also looked at reversing problems.

For example:

4 x 3 is the same as 3 x 4

so

4 + 4 + 4 is the same as 3 + 3 + 3 + 3

They were super clever and did a great job! Check out some photos of us working hard today.

Te Rōpū Tapaono (The Hexagon Group)

We have all been very busy solving + and - problems in a range of different ways. Check out what Te Rōpū Tapaono have been learning over the past few weeks:

We have been learning the following things:

Strategy:

Adding and subtracting in ones and tens (place value) e.g.

24 + 62 = ?

20 + 60 = 80 (add the tens together)

4 + 2 = 6 (add the ones together)

80 + 6 = 86 (add both sums together)

so 24 + 62 = 86

Rearranging numbers to find compatible numbers e.g.

70 + 20 + 20 + 30 + 80 =
70 + 30 = 100
20 + 80 = 100

We have 20 left therefore:

100 + 100 + 20 = 220

Subtracting in parts e.g.

24 - 7 = ?

24 - 4 = 20 (subtract back to a tidy number)

20 - 3 = 17 (subtract the remaining number - we had 3 left because we had taken 4 from 7)

so 24 - 7 = 17

Number Knowledge: 

- Know how many groups of 10 are in numbers up to 1000

- Say 100 before and 100 after for numbers up to 1000

- Practising our subtraction facts to 10 (so that we have instant recall)

Here are three of our group members showing us their tidy book work, what a great effort Jacob, Hannah E and Brooke!

WALT solve + and - problems by splitting numbers to make tidy 10s

Today the Tapatoru group were learning to split numbers to make tidy tens. Lucy caught on super fast and by the end of the lesson she was using this strategy without materials. She was even solving problems that involved larger numbers too, isn't she clever!

Miss Osborn was really proud of all of our group today, she thinks we did a fantastic job of splitting numbers!

WALT make 10

For homework this week, we are learning to make 10 in as many ways as possible. Today we learnt how to play the game Make 10. So far, three cards is the largest number of cards used to make 10. I wonder who will beat the record by the end of the week?

Check out some of our mathematicians learning to play this fun and competitive number knowledge game:
