In mathematics, an inequality is a relation which makes a non-equal comparison between two The relation "not greater than" can also be represented by a β― b, the symbol for "greater than" bisected by a slash, "not". The same is true for "not.

The meaning of these symbols can be easily remembered by noting that the ββbiggerβ side of the inequality symbol (the open side) faces the larger number.

Inequality tells us about the relative size of two values. Mathematics is not always about Symbol. Words. Example Use. > greater than. 5 > 2. <. less than. 7 < 9.

Printer-friendly version.{/INSERTKEYS}{/PARAGRAPH} If so, these are displayed face up in front of them. It is important for students to understand that symbols help us to express relationships between numbers and that equivalence is just one such relationship. Activity 3 Make available to the students, small pieces of card the same size and felt pens or pencils. Your child will explain how to play, Fish for Four. Session 1 SLOs: Understand the equals symbol as an expression of a relationship of equivalence, and explain this. Activity 2 Make plain A4 paper, felt pens, and cubes available to students. Explain that the students must listen very carefully to the story. Home Resource Finder. Activity 4 Conclude this session by reviewing key learning from this series of three lessons. The winner is the player with the most complete sets when all cards are used. On the class chart write, and have students in pairs, read this expression of inequality to each other. Make unifix cubes available to the students, and tell them to think of their favourite number between and including one and ten. NA Communicate and interpret simple additive strategies, using words, diagrams pictures , and symbols. Description of Mathematics. Players check to see if they have any complete sets in their hand. Go fish. Each player then privately identifies which set they will collect and they take turns to ask one other named player for a specific card to complete their set. {PARAGRAPH}{INSERTKEYS}The purpose of this unit of three lessons is to develop understanding of how to recognise and record relationships of equality and inequality in mathematical situations. Have students discuss these in pairs and decide which symbol goes with which pair of phrases and why they think that. This symbol tells us that two amounts are equivalent. Explain that there are more relationship symbols , and that they will learn about two more in this session. Each student should now have written at least 4 pairs of cards, 16 cards in total for the pair. The difference is zero. We hope you enjoy playing Fish for Four , and enjoy helping your child to practice their learning about inequality expressions and number relationships. There is no difference. The activities suggested in this series of lessons can form the basis of independent practice tasks. Home Link. Have pairs, or fours, play Fish for Four with one set of cards. Cities can be dismantled. Inequality is the relationship that holds between two values when they are different. Have the students join their cubes to make buildings for this city. The difference is six. Conclude the session by reviewing the four relationship symbols, one of equality and three of inequality, that have been used in Sessions 1 and 2. Explain that they are to write a difference card , and a subtraction equation card as shown in Activity 3, Step 1 for each of their inequality expression pairs. Make plain A4 paper, felt pens, and cubes available to students. Unifix cubes Street map diagram a simple, made up one , A1 or A2 size, for example: Small blank cards. Have students compare their expressions and equation in pairs. Read the story once. Ask if anyone knows any familiar buildings that might be the same height. It is then the turn of the next player. For each discuss and record the difference. Use the resource finder. Activity 5 Conclude the session by reviewing the four relationship symbols, one of equality and three of inequality, that have been used in Sessions 1 and 2. Have student pairs retain their maps for Session 2. Point out that we have been comparing and describing the buildings in relation to one another. Purpose: To recognise equivalent pairs of inequality expressions, and their matching subtraction equation and difference statements How to play: Cards are shuffled. Through exploring both equality and inequality relationships, and the symbols used to express these, students develop an important and heightened awareness of the relational aspect of mathematics, rather than simply holding the computational view of mathematics that arises from the arithmetic emphasis that is dominant in many classrooms. The difference is ten. Write these symbols on the class chart. Read this together. Show a skyline picture such as this and ask what features the students notice. Sets of cards can be used as an independent consolidation task. Ask students to explain this, giving examples from their own life, and record their ideas. These can be put together in a bag, or combined with an elastic band. Elicit descriptive, comparative language: tall, taller, tallest, short, shorter, shortest, same. Five are dealt to each player. Two is one less than three. Algebra is the area of mathematics that uses letters and symbols to represent numbers, points and other objects, as well as the relationships between them. The spare cards are put in a pile, face down, handy to all players. Required Resource Materials. But sometimes numbers or amounts are not equal. Activity 1 Begin by talking about buildings in your school, suburb, town, city, or a city nearby. Have student pairs exchange full sets of cards. In maths we mostly write equations. Share and discuss these as a class, recording them on the class chart. Place a simple city street map in front of the students, or create one with them. How do you know? List any tall buildings which are known by name. Log in or register to create plans from your planning space that include this resource. Recognise and describe in words the relative size of amounts. Explain we will be investigating relationships between numbers. They have made their own card games to play with you at home. NA Communicate and explain counting, grouping, and equal-sharing strategies, using words, numbers, and pictures. Specific Learning Outcomes. Activity 4 Have students shuffle the cards they have made in Activity 3, Step 2 above and swap these with another student pair. Fifty is ten less than sixty. Ask them to take this number of cubes of one colour. Understand how to find and express the difference between unequal amounts. Highlight an example eg. Zero is six less than six. As they do so, they should record relationship expressions, in order, for any numbers that they hear. Conclude this session by reviewing key learning from this series of three lessons. Highlight the fact that when we solve a subtraction problem, we are finding the difference. Accept all ideas. Understand the equals symbol as an expression of a relationship of equivalence, and explain this. Have students now identify towers that are not the same in height. The difference is one. For the pair, there are now 32 cards in total, 8 sets of four cards. They should draw at least four pairs of buildings and for these, write both equality and inequality statements in words and symbols , as modelled in Activity 1, Step 5 above. For example, one student takes seven pink cubes. AO elaboration and other teaching resources.
