Lesson summary

This week, we are going to revise and consolidate all the important Mathematics concepts we've learned so far in Grade R. This is like putting all the pieces of a puzzle together to see the whole picture. We will be revisiting counting, number recognition, shapes, patterns, and simple addition and subtraction. Understanding these concepts is very important because they form the building blocks for everything else you will learn in Mathematics in the future. Just like knowing your ABCs helps you read and write stories, these basic math skills will help you understand and solve everyday problems, like sharing sweets with your friends or knowing how many toys you have.

Lesson notes

2.1 Counting and Number Recognition (1-20): Counting is the foundation of all math. We use numbers to represent quantities. It's not just about saying the numbers in order, but understanding what each number means.

One-to-one correspondence: This means matching one number word to one object. When counting, make sure each object gets counted only once.

Cardinality: This means understanding that the last number you say when counting a group of objects tells you how many objects there are in total.

Example 1: Counting Oranges Imagine you have a basket with 7 oranges. To count them, point to each orange and say the number: "One, two, three, four, five, six, seven." The last number you said, "seven," tells you there are 7 oranges in the basket.

Example 2: Number Recognition You see the numeral "12" written on a page. This represents twelve objects. We can represent this with twelve small stones, twelve bottle caps, or twelve drawings of smiley faces. 2.2 2D Shapes (Circle, Square, Triangle, Rectangle): Shapes are all around us! Understanding shapes helps us describe and understand the world we live in.

Circle: A round shape with no corners or sides. Think of the sun, a soccer ball, or a coin.

Square: A shape with four straight sides that are all the same length, and four corners (vertices). Think of a window or a tile.

Triangle: A shape with three straight sides and three corners (vertices). Think of a slice of watermelon or the roof of a house.

Rectangle: A shape with four straight sides and four corners (vertices). Opposite sides are equal in length. Think of a door or a book.

Example 1: Shape Hunt Look around the classroom (or your home). Can you find a circle? (Maybe the clock). Can you find a square? (Maybe a book).

Example 2: Shape Sorting You have a collection of blocks that are circles, squares, triangles, and rectangles. You need to sort them into different piles based on their shape. 2.3 Patterns: Patterns are sequences that repeat. They help us predict what comes next.

Repeating Pattern: A pattern that has a core that repeats over and over again.

Example 1: Colour Pattern Red, Blue, Red, Blue, Red, Blue… What comes next? (Blue)

Example 2: Shape Pattern Circle, Square, Circle, Square, Circle, Square… What comes next? (Square) 2.4 Addition and Subtraction (up to 10): Addition means putting things together. Subtraction means taking things away. Addition (+): Combining two or more groups to find the total.

Subtraction (-): Taking away a part of a group to find what is left.

Example 1: Addition You have 3 apples, and your friend gives you 2 more. How many apples do you have in total? 3 + 2 = 5 apples.

Example 2: Subtraction You have 5 sweets, and you eat 1 sweet. How many sweets do you have left? 5 - 1 = 4 sweets. 2.5 Positional Language: Positional words describe where things are in relation to each other.

Above: Higher than something else.

Below: Lower than something else.

Next to: Beside something else.

In front of: Closer to you than something else.

Behind: Further away from you than something else.

Example 1: Where is the teddy bear? The teddy bear is on top of the table. The book is under the table.

Example 2: Simon Says "Simon says, put your hands above your head." "Simon says, put your hands behind your back." Guided Practice (With Solutions)

Question 1: Count the number of bananas in the picture: 🍌🍌🍌🍌🍌🍌🍌🍌. Write down the numeral that represents the number of bananas.

Solution: There are 8 bananas. The numeral is

8. Commentary: This question reinforces counting and number recognition.

Question 2: Draw a circle, a square, and a triangle.

Solution: (Learners draw the shapes).

Commentary: This question assesses the learner's ability to recall and represent basic 2D shapes. Ensure that each shape is identifiable, though perfect accuracy is not required at this stage.

Question 3: Complete the pattern: Green, Yellow, Green, Yellow, ____, ____.

Solution: Green, Yellow, Green, Yellow, Green, Yellow.

Commentary: This question tests the ability to identify and extend a simple repeating pattern.

Question 4: You have 4 marbles. You give 1 marble to your friend. How many marbles do you have left? Use your fingers or draw pictures to help you.

Solution: You have 3 marbles left. 4 - 1 =

3. Commentary: This question assesses subtraction skills using a real-life scenario.

Question 5: The cat is _____ the box. (The cat is inside the box.)

Solution: The cat is inside the box.

Commentary: This question reinforces positional language. Independent Practice (Questions Only)

Count the number of stars: ⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐. Write down the numeral. Draw a rectangle.

Complete the pattern: Apple, Orange, Apple, Orange, ____, ____. You have 6 cookies. You eat 2 cookies. How many cookies do you have left? The ball is _____ the chair. (The ball is under the chair). What shape is a road sign that tells you to stop? Write the number that comes after
