Calendar Maths

Calendar Maths is part of our daily programme in Room 11.

So much so that we are not allowed to have a day go by without doing it. We use a calendar to learn the names of the months, days of the week and to learn about the structure of a week, a month and a year. Today, tomorrow, yesterday and weekend are learnt in relation to the cycle of days. The sequence of months is learnt as well as the grouping of the months into seasons. Both Te Reo and English are used to say the dates, days of the week, months and seasons. Store bought calendars can be used. I make my own calendar using English and Te Reo.

Calendar Maths is also a great way to master basic maths skills through repetition. The basic maths skills we practice are related to the date and different ways to show this number. Some of the practice activities we do are before/after/between numbers, 10 less and 10 more, teen numbers, counting forwards/backwards, sequencing numbers, greater/less than, place value, doubles, basic facts of, tally marks, numeral formation, counting in 2’s/ 5’s/10’s, odd/even numbers. Some of the equipment we use is 10’s frames, 10’s beads, abacuses, number fans, hands, fingers, dice, counters and digit cards.


Group 3

The children practice their Maths Talk Moves: revoicing, repeating, reasoning, adding on, waiting, turn & talk.

The children also have the opportunity to use math vocabulary words to explain problem-solving. They love working out how many days until an event. We mark on the calendar upcoming events like discos, holidays, class trips, swimming, mufti days, the end of a season and the start of another.

Additionally, Room 11 is counting 100 days of being at school. This is also a great way to practice basic math skills and gives the opportunity for different levels of skills to be practised. The children have learnt that weekends and holidays are not included in the count - only the days we are at school. At the end of !00 days, we are going to celebrate our learning with a party! Presently, we have 90 sticks ( 9 bundles of 10 sticks). Room 11 knows that we only need 10 more sticks to reach 100. The question is will we reach the goal before or after the holidays?

So, I like the beads because you can grab the piece that you want and pull it down. You have to keep the hook on the other loop. You count with the beads in 10’s. I do good with the beads. Louie

I think I’m good at doing Maths because I know some of the numbers to 100. I like doing the tally marks because you can do lines instead of the numbers. Riley

I like to count to 100. I like doing the tally marks because you can count them by 5’s - 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85. 90. 95, 100, 105, 110. I want to get better at counting by 5’s backwards.

Learning about time takes lots of practice. Room 11 thinks that calendar maths is a fun way of doing this.
