Learning About Shapes: A 2 week unit of lesson plans on 2D and 3D shapes for F/1/2Australian Curriculum Lessons
This document is designed to expand on and broaden student’s knowledge of two-dimensional and three-dimensional shapes. The lessons are designed for students to not only learn shape names, but the features of shapes with a lot of the lessons emphasizing on the following feature concepts; sides, corners and edges. This fits seamlessly into the Australian Curriculum where the aim is for students to be provided with educational opportunities to describe shapes and objects using everyday words such as ‘corners’, ‘edges’ and ‘faces’. Overall the aim is for students to recognise and classify familiar two-dimensional shapes and three-dimensional objects using obvious features. The lessons throughout this document cater for Gardner’s Multiple Intelligences as they are diverse in nature and cater for many different learning styles.

Multiplication Explorers Online Course - Natural Math
This is a self-paced course. Multiplication is our most requested course topic – and it’s so much more than times tables! We are going to do something very new, to us and to the online course format in general. We love to read notes from participants explaining why they join, so here are a few: I hope to solidify my 5th grader’s multiplication skills and introduce it to my first grader and maybe even four-year-old. – AliciaAlways looking for engaging ways to help my son (with poor working memory) to learn about multiplication – preferable without the reliance on rote learning!

Joel David Hamkins
My recent talk, Playful Paradox with large numbers, infinity and logic, was a romp through various paradoxical topics in mathematics and logic for an audience of about 150 mathematics and philosophy undergraduate students at Fudan University in Shanghai, and since Fudan is reportedly a top-three university in China, you can expect that the audience was sharp. For a bit of fun, and in keeping with the theme, we decided to hold a Largest-Number Contest: what is the largest number that one can describe on an ordinary index card? My host Ruizhi Yang made and distributed announcement flyers for the contest a week before the talk, with a poster of the talk on one side, and a description of the contest rules on the other, and including a small card to be used for submissions. The rules were as follows: Example submissions: The population of Shanghai at this moment.

30 Techniques to Quiet a Noisy Class
One day, in front 36 riotous sophomores, I clutched my chest and dropped to my knees like Sergeant Elias at the end of Platoon. Instantly, dead silence and open mouths replaced classroom Armageddon. Standing up like nothing had happened, I said, "Thanks for your attention -- let's talk about love poems."
Minecraft Multiplication Practice - Christy's Houseful of Chaos
Are you looking for ways to convince your children to practice their multiplication facts? There are many places to get minecraft flashcards with random minecraft pictures and random multiplication facts, but I wanted a way in which to give my seven year old more practice with the multiplication that is integral to minecraft itself. I decided to work on just the multiples of four and six and I devised both some instructions for him to work through on the computer and a set of cards to play with at the kitchen table.

Algebraic thinking
Developing algebraic ideas and language Number tricks are fun for children. The fun, all by itself, is valuable, but is not mathematics. But understanding how the trick works is good mathematical, often algebraic, learning.
you clever monkey: One is a Snail, Ten is a Crab
I've used the picture book One Is a Snail, Ten is a Crab: A Counting by Feet Book (affiliate link) a few different ways now. It's such a great book with beautifully bright illustrations, many different number uses and a sense of humour making it a great read aloud book for all ages. I love using books in lots of different areas other than English and this one is perfect for Maths. This term I used it to help support number sense in the classroom. I knew that both year levels had done some work around skip counting (counting by 2s and 5s) last term so I used this text early in the first week of term as a review.
