Today we played a simple game with two dice to practice our skill of counting on when adding.
What is the count on method?
Counting on is a mental math skill where, when adding two numbers, you begin counting from the largest number and add the second number to it. Counting on helps us figure out how many more we need of something and how many we will have once more is added.
Today we used a fabulous book called Two Of Everything by Lily Toy Hong as our focus in our math lesson. This book retells a Chinese Folktale with great humour. The story is about Mr. Haktak who digs up an ancient brass pot and brings it home to his wife. While the Haktak's can't find any particular uses for the pot, they discover it has magical powers. The magical pot doubles everything. In the end, the Haktaks find a way to wield the magical pot powers. After enjoying this book and discussing items that we would love to have doubled, we used the concept to practice double addition facts. For example, When Mr. Haktak accidentally drops his coin purse containing 5 coins in the pot, the 5 coins are transformed into 10. The grade one practiced their double facts up to 6+6, and then 10+10 as an added challenge. The grade two's practiced their facts up to 10+10 and then an added challenge of any number up 50 using addition with regrouping when required.
Today we had a dynamic conversation about ways that we can protect our water source. The students have a lot to say and are very passionate about conserving this invaluable resource. Many of the children asked if I could send the video we watched to their parents. So I thought I would pass on the link that generated such a great debate in class. https://youtu.be/Om42Lppkd9w Please take the time to discuss with your child what small steps they would like to make to help contribute to the protection of our water source.
Today our grade two class started to learn how to add two-digit numbers with regrouping. To break this task down into simple steps that are tactile as well as visual we started by learning the process using math manipulatives.
