# Maths We follow a maths mastery approach at St. George's and as such, we are spending a long time on number (place value), addition and subtraction. When we are secure in the Year 4 concepts, we will move on to incorporating more complex ideas into our lessons, always drawing on previous learning in order to make connections. The aim is to become fluent in number facts, be able to represent what we know in many different ways and make links between areas of knowledge - thus becoming maths masters!

At St. George's, we believe everyone can master maths.

With hard work and encouragement, we can all achieve!

#### During  Autumn 2 we are focusing on spine 1- Number, Addition and Subtraction

We will be studying:

Topic 1.24 Composition and calculation: hundredths and thousandths

• Teaching point 1: When one is divided into 100 equal parts, each part is one hundredth of the whole. When one tenth of a whole is divided into ten equal parts, each part is one hundredth of the whole.

• Teaching point 2: Hundredths can be expressed as decimal fractions; the number written ‘0.01’ is one hundredth; one is one hundred times the size of 0.01; 0.1 is ten times the size of 0.01.

• Teaching point 3: We can count in hundredths up to and beyond one.

• Teaching point 4: Numbers with hundredths can be composed additively and multiplicatively.

• Teaching point 5: Numbers with tenths and hundredths are commonly used in measurement, scales and graphing contexts.

• Teaching point 6: Known facts and strategies, including column algorithms, can be applied to calculations for numbers with hundredths; the same approaches can be used for numbers with hundredths as are used for numbers with tenths.

• Teaching point 7: Numbers with hundredths can be rounded to the nearest tenth by examining the value of the hundredths digit or to the nearest whole number by examining the value of the tenths digit.

Topic 1,25 Addition and Subtraction: Money

• Teaching point 1: One penny is one hundredth of a pound; conventions for expressing quantities of money are based on expressing numbers with tenths and hundredths.

• Teaching point 2: Equivalent calculation strategies for addition can be used to efficiently add commonly-used prices.

• Teaching point 3: The ‘working forwards’/‘finding the difference’ strategy for subtraction is an efficient way to calculate the change due when paying in whole pounds or notes.

• Teaching point 4: Column methods can be used to add and subtract quantities of money.

• Teaching point 5: Finding change when purchasing several items uses the part–part–(part–)whole structure.

I will continue to set Mathletics homework each week. It will be set on Friday and will be due the next Wednesday. It will always complement the work we are doing in class.

Children, if you don't understand something, click the 'i' in the top-tight corner. This will give you an explanation if you follow the arrows on the right. # We would love to hear from you!
