Question: Mpho turned 5 years on the 3rd of February. His mom decided to have a party at school with all thirty children in his class. But on the day of the party, 2 more children were enrolled in Mpho’s class. Mpho’s mom provided only 30 cupcakes, 30 sweets, 30 apples, and 6 2-litre bottles of orange juice – exactly enough for thirty children. Mpho had a big, rectangular birthday cake decorated with colourful Smarties. After the party, the children had fun playing outdoor games in groups of five. Identify five mathematical concepts that can be developed through Mpho’s party.

Certainly! Mpho's birthday party scenario provides a great opportunity to introduce and reinforce various mathematical concepts. Here are five key concepts that can be explored: 1. **Addition and Subtraction**: - Number of children: The addition of two new children to the original 30 can be used to introduce the concept of addition (30 + 2 = 32). - The concept of subtraction can be looked at when considering how many cupcakes, sweets, and apples are short (32 - 30 = 2). 2. **Division and Remainders**: - Distribution of items: With only 30 cupcakes, sweets, and apples for 32 children, students can discuss how to divide those items and what happens when there are not enough for everyone (30 ÷ 32 = 0 remainder 30, illustrating the concept of insufficiency). - Sharing the cake and orange juice evenly among the 32 children can also bring in division. 3. **Multiplication**: - Number of items: Calculate the total number of sweets, apples, and cupcakes bought. For example, 30 cupcakes + 30 sweets + 30 apples = 90 items. - Groups of children playing: Organizing children into groups of five can illustrate multiplication (5 groups of 5 children for 25 children, with some groups having different arrangements to incorporate all 32 children). 4. **Fractions**: - If the birthday cake is cut into equal pieces, you can discuss fractions. For example, if the cake is cut into 32 pieces, each piece represents 1/32 of the whole cake. - Considering how each child gets an equal share of 6 bottles of juice (each 2 litres), you can explore how to divide these litres among 32 children. 5. **Geometry and Measurement**: - Discussing the shape of the birthday cake (rectangular) can be an introduction to geometry. - Measuring the amount of orange juice in litres and discussing volume and capacity (each 2-litre bottle) can introduce basic concepts of measurement. By exploring these concepts in a real-life context like a birthday party, children can see the relevance and application of mathematical ideas in everyday situations.
