Learn about 100 and Celebrate 100 Days Of School

The Australian school year consists of approximately 200 days. Depending on the length of terms and number of public holidays in each, the 100th day often falls towards the beginning of the third term in July. Knowing that many of you will be preparing to celebrate the 100th day with lessons investigating 100, I thought I’d share our readilearn resources that support you with that. It’s always exciting to count the 100th day, because once it’s reached, it’s time to start counting down to the end of the school year, which get closer with every day.

Celebrating 100 days of school

lessons and activities for celebrating 100 days of school

Although Busy Bees celebrate 100 days of school suggests ways of counting the days from day one, it also suggests ways of celebrating when the 100th day arrives. Suggestions include: count and collage 100 items and decorate a cake with 100 candles. There are party suggestions and an original game to play. (Also included with purchase of the Busy Bees 100 chart.)

It is a Word document that can be personalised with your name and class before printing and distributing. (Also included with purchase of the Busy Bees 100 chart.)

Teaching numbers up to 100

developing understanding of number with an interactive 100 board

The interactive digital resource Busy Bees 100 chart is great for all your usual number board activities. Perhaps you’ve already been using it to keep track of how many days you’ve been at school. Now that we’re halfway through the year, you can use it in a similar way to count down the number of days left in the school year.

Collect 100 flowers for Busy Bee – a counting game  reinforces understanding of numbers to 100. It involves children in taking turns, rolling a dice, making tallies, counting to 100, and adding or counting tallies. Played alone or with others, it is ideal as a maths group activity. (Also included with purchase of the Busy Bees 100 chart.)

100 Ladybirds  helps children develop an idea of the size of a collection up to 100. The lesson begins with 0 ladybirds on the screen and the numeral 0 in the top right-hand corner. Children click on the leaf to add one ladybird to the screen. As each ladybird is added, the total changes commensurately until the number reaches 100.

teaching place value using the train game

Beginning place value – the train game ensures children develop a good understanding of number and our decimal number system, essential for success with maths. It is a fun but effective way of ensuring that children develop an understanding of place value.

Fill Mrs Bilby's Wagon cover

Fill Mrs Bilby’s Wagon is a game that provides opportunities for children to engage with the following mathematical concepts:

  • Subitising: the numbers on the dice, and the number of eggs in their baskets
  • Adding: the numbers if two dice are rolled, the number of eggs to their baskets
  • Counting: in ones the number of eggs in their baskets, in tens the number of eggs in their trays
  • Finding missing addends: how many more until I have ten, how many more boxes until I have ten boxes, until I have 100 eggs
  • Trading: ten ones for one ten

To 100 and beyond

Understanding place value of 3-digit numbers

Let’s Count Pancakes — 3-digit numbers supports children’s understanding of place value with 3-digit numbers. Children learn to recognise and represent 3-digit numbers and understand the value of each numeral in its place.

1000 Pancakes gives children the opportunity to visualise 1000 pancakes by comparing the quantity to 10 and 100. First the children count pancakes in 1s to 10. Next, the children count pancakes in 10s to 100. Then they count pancakes in 100s to 1000.

    Children feel so proud of themselves when they can count to one hundred. I’m sorry the ideas are too late for you and your children. (and much too soon for any grandchildren 😉)

Please share your thoughts. I love it when you do.
