Multiplication, Report writing & Spooky houses

Today in math we practiced what we learned yesterday about multiplication. Yesterday we solved some problems involving multiplication of larger numbers, specifically 3 digit by 2 digit numbers. We learned three ways to multiply:

1) Break apart method; 198 x 23

• 8 x 3 = 24
• 90 x 3 = 270
• 100 x 3 = 300
• 8 x 20 = 160
• 90 x 20 = 1800
• 100 x 20 = 2000
• added together 2000 + 1800 + 160 + 300 + 270 + 24 = 4554

2) Lattice multiplication: Click here for video explaining

3) Standard method: Here

I encouraged students to use whichever method works for them, but to be aware that there is more than one way to multiply. When they do EQAO, the focus is not so much on being able to multiply, but rather being able to solve problems involving multiplication, including multi-step problems that combine concepts from a variety of strands (eg. number sense and measurement). This is something we will be practicing a lot this year. 

In language, we are working on writing reports using an essay format by following an outline. Today, we finished writing a report about Great White sharks in groups using an outline at the front of the class. Then we did a "gallery walk" and looked at the work others groups did using the same outline. Students were encouraged to make comments to help each group improve their work. Tomorrow, we will be writing report individually from a common outline that I will provide. Then they will use the success criteria developed in class to improve their work, along with the bump it up wall. 

In art today, we started working on "Spooky Houses" for Halloween. Students first have to make a house and colour it black, with yellow windows. Next we will paint the backgrounds using watercolours for the sky. Here is an example of what I am hoping they will turn out like:
