Ling was doing the below exercise and she got confused whether bamboo has woody stem or soft stem. (竹子是属于草质茎还是木质茎？) Actually I am very confused too.

After googling and the below explanation makes the most sense for me :

草木之别的关键要看是否有“年轮”。木本植物每过一年，茎干的横断面便增添一圈同心轮纹，然而锯断竹子看，里面却空空如也。由此可知，竹子是“草”。而非“树”。竹子属禾本科多年生常绿植物，与稻、稗等同属一科

The difference between ‘woody stem’ and ‘soft stem’ is the existence of ‘tree ring’. By looking at the cross-section of a ‘woody stem’ plant, you can see the annual rings formed due to the growth of the stem(trunk). When you saw a bamboo stem, it’s empty inside. Therefore, bamboo is ‘grass’ and not ‘tree’. Bamboo belongs to the same group as paddy and millet.

Before we start on Addition and Subtraction, let’s watch this wonderful video from Math Is Fun website, about Equivalent Fractions. It’s a must to understand and master this concept of Equivalent Fractions before we can proceed to + and -.

Now, let’s start with Addition.

$addfraction$

Here is another good demonstration of how to do Addition in Fractions

And now, let’s move on to Subtraction. The rule is quite similar to Addition.

$subfraction$

Lastly, more challenging one:

Vola! There we go. 🙂

And you can try out some exercises from the link below:

I think it’s good to go through the English terms for Fraction with the girls, as well as making sure they understand the 3 different types of fraction, before I proceed to do Equivalent and Comparison.
