今天讓小朋友做數字聖誔樹。樹上有四顆彩球，媽媽給了公主和王子各三個數字，讓他們用這三個數字寫出四種不同的算式（加和減）。當然，弟弟的媽媽幫了些忙（有用教具引導他算），姐姐的呢，就是她自己想出來的（最後一個媽媽有給提示）。最後呢，小朋友們還裝飾了他們的樹。當然，從不按牌理出牌的弟弟呢，還用剪剩的紙做了一塊泥土給樹站在上面，真服了他。
姐姐的：(6, 3, 9) –> 6+3=9, 3+6=9, 9-3=6, 9-6=3
後來姐姐覺得很好玩，又和我要了一顆樹，我又給了她一組數字：8, 4, 12
弟弟的：2, 4, 6
Today we did a fun math project. I gave each children 3 numbers, and the goal is to think of four different math sentences using these 3 numbers. Katharina pretty much did this on her own, and for Alexander I gave a little help. They each then decorated their trees. Alexander of course had to do something different, he made a soil for the tree to stand on (that was unplanned but awesome idea!).
