# 3.10 Work with squares and circles

 Page 1 / 1

## Critical and developmental outcomes:

The learners must be able to:

1. identify and solve problems and make decisions using critical and creative thinking;

2. work effectively with others as members of a team, group, organisation and community;

3. organise and manage themselves and their activities responsibly and effectively;

4. collect, analyse, organise and critically evaluate information;

5. communicate effectively using visual, symbolic and/or language skills in various modes;

6. use science and technology effectively and critically, showing responsibility towards the environment and the health of others;

6. demonstrate an understanding of the world as a set of related systems by recognising that problem-solving contexts do not exist in isolation;

7. reflect on and explore a variety of strategies to learn more effectively;

8. participate as responsible citizens in the life of local, national, and global communities;

9. be culturally and aesthetically sensitive across a range of social contexts;

10. explore education and career opportunities; and

develop entrepreneurial opportunities.

Integration of Themes:

• Inclusively and Human rights: Everyone in a class deserves to be challenged. Special creative work should not be given to the bright learners only. Opportunities to extend, to experiment and to discover should be present to everyone in the class. This will encourage learners to try new methods, to learn from their peers and to take risks. Discuss in small groups whether we should be given work to make us think.
• Practical experience with halves and quarters is given.
• Number concept is extended beyond 200 and counting patterns stressed.
• Learners are carefully guided to understand the rounding off of numbers to the nearest multiple.
• Bonds of 17, 18 and 20 are introduced.
• Number values and place values are taught with diagrams.
• The multiplication tables of 10 and 5 are set out.
• Learners can create their own patterns, and games for consolidating number facts are included.
• Using their imagination they can create animals, using shapes.

## Content

ACTIVITY: Work with squares and circles[LO 1.2, LO 1.3, LO 1.9, LO 2.2]

• Add up all the numbers in the square to make the total in the circle.
• Complete the squares.
 LO 1.9
• Each diagonal must have the same total.
• Use different numbers.
 LO 1.9
• Complete the number sequence in each block.

 LO 1.2 LO 2.2
• Complete the number block.
 101 102 180
• Count in ones from 101 to 180.
• Count backwards from 180 to 101.
• Count in tens from 110 to 180.
• Count backwards in tens from 180 to 110.
• Count in fives from 105 to 180.
• Count backwards in fives from 180 to 105.

## Assessment

Learning Outcome 1: The learner will be able to recognise, describe and represent numbers and their relationships, and to count, estimate, calculate and check with competence and confidence in solving problems.

Assessment Standard 1.2: We know this when the learner counts forwards and backwards;

Assessment Standard 1.3: We know this when the learner knows and reads number symbols from 1 to at least 200 and writes number names from 1 to at least 100;

Assessment Standard 1.9: We know this when the learner performs mental calculations.

Learning Outcome 2: The learner will be able to recognise, describe and represent patterns and relationships, as well as to solve problems using algebraic language and skills.

Assessment Standard 2.2: We know this when the learner copies and extends simple number sequences to at least 200.

The denominator of a certain fraction is 9 more than the numerator. If 6 is added to both terms of the fraction, the value of the fraction becomes 2/3. Find the original fraction. 2. The sum of the least and greatest of 3 consecutive integers is 60. What are the valu
1. x + 6 2 -------------- = _ x + 9 + 6 3 x + 6 3 ----------- x -- (cross multiply) x + 15 2 3(x + 6) = 2(x + 15) 3x + 18 = 2x + 30 (-2x from both) x + 18 = 30 (-18 from both) x = 12 Test: 12 + 6 18 2 -------------- = --- = --- 12 + 9 + 6 27 3

on number 2 question How did you got 2x +2
Ifeanyi
combine like terms. x + x + 2 is same as 2x + 2

Mark and Don are planning to sell each of their marble collections at a garage sale. If Don has 1 more than 3 times the number of marbles Mark has, how many does each boy have to sell if the total number of marbles is 113?
Mark = x,. Don = 3x + 1 x + 3x + 1 = 113 4x = 112, x = 28 Mark = 28, Don = 85, 28 + 85 = 113

why surface tension is zero at critical temperature
Shanjida
I think if critical temperature denote high temperature then a liquid stats boils that time the water stats to evaporate so some moles of h2o to up and due to high temp the bonding break they have low density so it can be a reason
