# Birthday Party

Purpose:

In this unit students help plan a party for Q-Bear and think about some of the different ways people celebrate their birthdays.

Specific Learning Outcomes:
• state when their birthday is and mark this on a calendar
• make a set of ten linking paper rings
• make groups of five using different combinations
• identify common ways people celebrate birthdays in New Zealand
Description of mathematics:

Reading a calendar and identifying specific dates

Number operations – counting from one, counting on, imaging etc. – practice in a variety of meaningful contexts

### A description of the social studies explored in this unit

This maths unit is written to work alongside the social studies unit Celebrating Birthdays that can be found on the Social Studies Online site. For a full description of the social studies concepts and associated activities please see:

http://www.tki.org.nz/r/socialscience/curriculum/SSOL/birthday/index_e.php

In general, students explore the importance of birthdays and find out some different ways birthdays are celebrated in different countries.

Associated Achievement Objectives

Social Studies AO5: understand how the cultures of people in New Zealand are expressed in their daily lives.

Required Resource Materials:
Calendars
Paper
Crayons
Cardboard to make crowns
Coloured paper to cut into shapes
Paper to make paper streamers, ideally crepe paper
Key Vocabulary:

calendar, birthday, birth date, date, day, week, month, year, first, last

Activity:

#### Introduction, Session 1

Introduce Q-Bear (or something similar) to the students and explain that he is going to be having a birthday soon. Show his birthday on the calendar, making it near the end of the unit to allow time for planning the party.

Have students locate their birthdays on a calendar and record the date.

Lead a discussion to encourage students to read the calendar and compare birth dates. For example

Who has a birthday close to Q-Bears?

How many days / weeks between the two birthdays?

Who is older, Jonah or Sally? By how many days?

Who has the first / last birthday of the year?

Explain that people all over the world have birthdays and celebrate them in their own special way.  What could we do to celebrate Q-Bear’s birthday?  Brainstorm and list these features, for example cake, candles, gifts, decorations, a feast, umu, hangi

#### Exploring, Sessions 2-4

Explain that Q-Bear is very excited about his birthday so as a class they are going to plan and hold a party for him. Carry out the following activities as preparation over the next few days.

Candles

Q-Bear is going to be 5 years old and there are red and blue candles for his cake. Draw the different colours his candles could be. For example, 5 red, 4 red and 1 blue or 3 red and 2 blue etc.

Record this information as pictures, written sentences or number sentences.

Shopping list

Q-Bear is going to invite 5 friends to the party. They will get 3 lollies and 2 balloons each to take home. How many lollies and balloons will you need to buy? Use counters or draw diagrams to help figure this out, adapting the numbers to make this problem harder as required.

Cupcakes

Q-Bear is very excited as he is going to have special cupcakes at his party. These cakes have 2 lollies on each one to look like eyes. If he ate one cupcake how many lollies would he eat? What if he ate 2 cakes? Or 3 cakes?

Record the pattern and practise skip counting.

Hats

Make a special crown to wear at the party. Provide students with 3 different shapes to decorate their crowns with, for example, squares, triangles and stars. Once the hats are finished count the numbers of shapes used on some of the crowns and record this. For example, Elisa used 3 stars, 4 triangles and a square on her crown. She used 8 shapes altogether.

Paper streamers

Make some paper streamers by joining lengths of paper together as interlocking circles; like a chain. If everybody makes 10 links how many will there be altogether? Have students carefully count 10 links as they make them, then count them all together at the end.

#### Reflecting, Session 5

Hold a party for Q-Bear with some special party food. Students could bring a plate, or the teacher could provide some items as required. Have students wear their hats and bring simple presents they have made.

Sing happy birthday or Ra whanau ki a koe to Q-Bear and play some party games.

After the party reflect and record some information about the party. For example

What date was Q-Bears birthday?

How many whanau and friends were at his party?

How many gifts did he get?

## Up we go

In this unit we work on word problems about climbing up steps and riding in a lift. We learn about different types of problems that can be modelled on number lines. We practice mental calculations with sums to 10 and to 20.

## Frogs in Ponds

In this unit students investigate the different number pairs that numbers can be broken into, using the context of frogs in ponds.   They list all possible combinations for a given number, working with numbers up to 9.

## Large Animals, Small Animals

In this unit students estimate the sizes of common farm animals and draw life-size diagrams of these animals. They also use non-standard measurement units to check their estimations and design appropriate shelter for some of these animals.

## Ten in the Bed

In this unit students will experience skip counting in twos and fives based on the common nursery rhyme “Ten in the Bed”.

## Dates and Shapes

These are level 3 number, measurement, and geometry problems from the Figure It Out series.
