Where appropriate, examples have been provided in brackets following an indicator. Subheadings have been included to group related indicators. The listing of indicators within each level is non-hierarchical. The abbreviation for this sub-element is QuN. This may include digital technologies, sign language, braille, real objects, photographs and pictographs.Įach sub-element level has been identified by upper-case initials and in some cases lower-case letters of the sub-element name followed by ascending numbers. Some students will communicate using augmentative and alternative communication strategies to demonstrate their numeracy skills. The Quantifying numbers sub-element underpins learning of number sense, measuring and using data. That is, the quantity represented by a numeral is the sum of the values represented by its individual digits (326 = 300 + 20 + 6) and the value of a digit is determined by multiplying its face value by the value assigned to its position in the numeral (326 = 3 x 100 + 2 x 10 + 6 x 1). In addition to the base-ten positional value property, the place value system has both additive and multiplicative properties. Place value relies on understanding the relationship between digits in a numeral, which then enables the numeral to be renamed in multiple ways. Within this sub-element, place value is taken to mean more than being able to read, write and state the positional value of a digit. Growing by Powers of Ten Chart Lets look at place value and powers of ten In this worksheet, students will work through a chart that helps them see the patterns within the powers of ten. It outlines key understandings needed to process, communicate and interpret numerical information in a variety of contexts. This sub-element describes how a student becomes increasingly able to count, recognise, read and interpret numbers expressed in different ways. National Literacy and Numeracy Learning ProgressionsĪlthough number is an abstract concept which can be represented by a word, a symbol (numeral) or an image, it is central to quantitative thinking.General capabilities and career education.Framework for Aboriginal Languages and Torres Strait Islander Languages.Supporting gifted and talented students.Asia and Australia’s Engagement with Asia.Aboriginal and Torres Strait Islander Histories and Cultures.If you start with 1 and move the decimal point 2 places to the left, you get 0.02. The following example uses the Pow method to calculate the value that results from raising 2 to a power ranging. This power of 10 has an exponent of negative 2. This is why there are 2 0s after the 1.Ī power of 10 can also have a negative exponent. If you start with 1 and move the decimal point 2 places to the right, you get 100. This power of 10 has an exponent of positive 2. It can be positive or negative.Īll the examples of powers of 10 we have seen so far have positive exponents. In this unit, you'll learn the patterns in multiplying and dividing by 10, 100, and 1000. The exponent tells you how many times the base is multiplying by itself. Math is all about patterns, and there's no better place to see that than with powers of ten. The base is the number that is multiplying itself. Read more about scientific notation The Parts of a Power of 10Ī power of 10 has the same parts as any power. This way of writing numbers is called scientific notation. A lookup table will be by far the fastest and most precise way to do this only about 600 powers of 10 are representable as doubles. The 0s come after a 3, so we need to multiply the power of 10 by 3.
