弟弟的數學功課！

老師的評語：Jayden, your work was amazing! I am so impressed with how well you are understanding fractions, multiples and factors. I gave you +1 for using multiples of 12, which was very clever. However, I took -1 because you did not show your multiplication to generate the equivalent fractions on the last problem. But you still made a 100! Keep up the amazing work!

熟悉英式單位的媽媽，雖然在美國住了十幾年，對於美式單位換算還是相當不熟悉，現在乘這個機會跟弟弟一起認真學習一下。

用 hundred chart 觀察 multiples 之間的關係！

黑框的是 multiples of 2，

紅圈的是 multiples of 3,

黃三角形是 multiples of 6。

觀察：2 X 3 = 6，所以 multiples of 6 are common multiples of 2 and 3。

弟弟不愛在 journal 寫字，喜歡用白板/在電腦上做功課，有些功課媽媽索性直接用 iPad 讓他完成，滿足他愛用電子產品做功課的興趣，也正好可以省下影印的費用。

Multiples of 2 都是偶數 even numbers，它們的尾數都是 0，2，4，6，8

數學 . Pi Day

在 Michaels 網站查找孩童網路美勞課程，發現一個新奇的 Pi Day Compass Art，搞不清是什麽，google了才發現是慶祝數學 Pi Day，3/14 也是 Elbert Einstein 的生日喔！想必家裡那位數學迷應該會很振奮吧！
