Here is a link to an inspiring video about the power of solving maths in groups and being a problem solver: https://www.youcubed.org/solving-math-problem/

Below is a video which shows that we can all learn Maths to high levels and that even the best Mathematicians in the world can be really slow to solve problems. How you do in Maths tests does not determine your ability in Maths, believe in yourself, work hard and take your time to solve Maths problems and you will make great progress.

We are learning to use critique and self-assessment in our artwork this week to create artwork better than we have created in the past.

The technique we are using is based of the following video: Austin’s Butterfly

We will share our results when we have finished.

Today we looked at how to create Mandalas and created our own creative artwork using this technique. Below is a video that explains the process.

Here is an insightful video showing us the importance of viewing learning and making mistakes in a positive way. Having a growth mindset sets us up for success.

**The ability to partition is essential to be at the maths standard for Year 4. **

In **Year 4** students are working towards being proficient at **Strategy Stage 5 (Early Additive)** in maths by the end of the year. One of the main skills of Strategy Stage 5 is the ability to add and subtract numbers by **partitioning** (breaking up) them rather than counting on or counting back (i.e. 5, 6, 7, 8, 9, 10, 11 … OR 12, 11, 10 9, 8…).

**Partitioning numbers** means we know that **we can break a number up into its basic facts** to help us solve problems. For example 7 can be broken up (partitioned) into two numbers:

7 = 3 + 4, or 5 + 2, or 6 + 1

Students at the Early Additive stage solve number problems by simple **splitting of the numbers (partitioning)** and by **using groupings of hundreds, tens and one**s (**simple place value**).

Students at this stage need to recognise that numbers can be split into parts and recombined in different ways. This is called **part-whole thinking**. Problems at this stage are usually limited to numbers less than 20, or where one of the numbers is a single digit.

Strategies used at this stage include:

**using doubles**

7 + 8 as (7 + 7) + 1**up through a ten**

38 + 7 as (38 + 2) + 5**compensation**

24 – 9 as (24 – 10) + 1.

Here is a video demonstrating Stage 5 Early Additive thinking (Year 4) by a Year 4 student.

**Note:** We can make **either number a tidy number** in the addition tidy number strategy.

**Note: We do the OPPOSITE to each number**, i.e. if we subtract on one of the numbers we add on the other number. The reason for this is because we take away some numbers from one of the numbers to round the other number.

For example if our addition problem was:

48 + 17 =

**STEP 1: Making a Tidy Number**

We first round the 48 up to 50 (because it is closest to a tidy number) by taking 2 off the 17. We are then left with the easier problem of:

50 + 15 =

The 15 is what is left after taking the 2 off the 17.

We can then partition up the numbers and add them together:

50 + 10 + 5 = 65

So we haved solved our problem:

48 + 17 = 65.

**Note:** We only make the **second** **number a tidy number** in the subtraction tidy number strategy. By making the second number a tidy number it becomes an easier problem to solve as there are less digits to subtract from the first number.

**Note: We do the SAME to each number **– both sides get bigger or smaller by the same amount. We are trying to work out the distance between the two numbers so we must do the same to both numbers to keep this gap the same.

For example, if our subtraction problem was:

48 - 17 =

**STEP 1: Making a Tidy Number**

We first round the second number which is 17 up to 20 by adding 3 to the 17.

We need to make sure we add 3 to the 48 as well so that the gap between the two numbers remains the same

(i.e. there is always a gap of 31 between the numbers in our example).

We are then left with the easier problem of:

51 - 20 =

**STEP 2: Using our basic facts to help us solve the problem**

We could now approach this problem by using our basic fact of

5 - 2 = 3 Therfore: 51 - 20 = 31

So we have solved our problem:

48 - 17 = 31

We have handwriting as part of our weekly activities in class. The style of **handwriting** the Ministry of Education recommends in its Teaching Handwriting handbook which develops from printing to the modern cursive handwriting style.

This term we are going to focus on printing to make sure we are forming all letters correctly.

Information about the handwriting curriculum and cursive writing is below.

The **uppercase** (capital) basic **cursive** script letters are the **same** as the basic printing uppercase (capital) letters and so don’t link to the lowercase letters. An example is below:

The difference between the basic script alphabet and cursive alphabet are in the letters f and x and in the exits of a, d, h, i, k, 1, in, n, o, r, t, u, v, and w. (Exit refers to the stroke that forms the beginning of the link to the following letter.)

**Some useful resources for practising modern cursive handwriting:**

A useful website with worksheets for practise with the for the modern cursive handwriting style is Ted Power.

A fun app for beginners to practise the modern cursive unlinked letter formations is Australian Touch and Write: Victorian Cursive app.

A useful document with great suggestions on proper grip, posture and handwriting instruction is the Handwriting South Australian Modern Cursive Handbook.

We will be looking at our grip when holding a pencil and the best position of our paper when writing in a cursive script. See the images below for examples of what we will be learning.

We will be moving from the Year 3 printing style to cursive. The difference can be seen below:

This is an interesting video which shows that science is proving we all have the ability to be good at Maths.
