4 digit multiplication
For the past few days our class has been doing 4 digit multiplication problems. They were really hard, and our class is still struggling with them. But in a few weeks I think we will have mastered those problems. We are doing the multiplication problems using the new math program, Singapore math.
An example: 4615

Math
We learned about factors and multiples this week. Factors are numbers you multiply like in the number 18, the factors are 1, 2, 3, 6, 9, and 18. Multiples are when you count by a number, for example, the multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 etc. We even learned about common multiples and common factors this week.

Factors…
This week we learned about factors. Factors are the two numbers that tell you what to multiply, for example, 1×4=4. The 1 is a factor and the 4 is a factor too. The answer is called the product. On Friday, we did factors for 4, 8, 12, 16, 20 and our challenge was 60.

All about rounding…
This week we learned about rounding to the nearest tens, hundreds, and thousands. “A lot of people found rounding difficult,” says local class kid Elior. I know will get better at rounding. Also on Friday, Mrs. Teitelbaum asked us for all the factors for 60. A lot of people got it wrong. It was challenging.

Math Tutorials
They say
If you can teach it…you know it!
We put 4th grade Math students to the “test”… well not really… No traditional test was required to show their understanding of multiplication. Based on Alan November’s work of “The Digital Learning Farm“, which he also outlines in his chapter of Heidi Hayes Jacobs’ book “Curriculum 21“, we asked our students to be Tutorial Designers.
We started our with a lesson on good tutorial design:
In groups, students set out to write scripts of their tutorials. Each group decided to use different tools to create a video visualizing the math problem and the step by step solution. We had one group creating a PowerPoint document, another one used sticky notes and the third group used various apps on the iPad to film and record.
The process of creating a simple tutorial was elaborate. From breaking the multiplication process up into individual steps, to being able to express these steps verbally and visually to creating a storyline around the math problem/solution to make it flow.
Take a look at the final product of each group.

Creating Math Tutorials
On Thursday, each Math group filmed their tutorial for the purpose of editing their scripts. Using the feedback from the class, each group will now edit their tutorial script and storyboard this week. The class has seen how important it is to be specific and concise in their explanations. The process continues!

Thinking Blocks
In order to help with problem solving skills, we worked with Thinking Blocks. Using interactive visual representations/models of word problems, Thinking Blocks guides the students with a strategy for solving word problems. We began by working problems together, then the class was divided into groups. Collaboratively, the group worked out a visual strategy to solve their word problem.
Each group shared their problem solving strategy using ELMO, the document camera. The Thinking Blocks website is listed as a link under the Math category on our blog.
