Matemáticas de 4.º grado: un enfoque basado en la resolución de problemas

This nontraditional, hands-on and discovery based course is perfect for a home-school curriculum or to use as a review. 

Students will explore number relationships by doing hands-on activities, looking for patterns, and solving complex problems.

There are three primary goals of this course:
1. Students to develop flexible math thinking (the ability to see relationships and use those relationships to solve problems in a variety of ways) 
2. Students to gain confidence in their problem-solving abilities
3. Students to gain not just school knowledge but real-life critical thinking and problem-solving skills.

Due to the nature of this course, it is important for students to come to class with their cameras on and be ready for discussion. 

Each class will follow the following format: Warm Up Activity that works on developing mental math skills, and number flexibility, a hands on activity or a complex problem for students to work through together, a summation of the key idea for the day, and an exit question (they will submit their answer privately in the chat) 
I will use this exit question as an informal assessment of your learner’s progress. 

I keep detailed notes of each learner's progress for their time in my classes. A transcript will be sent with personalized information at the end of the semester. 

Please note: There will be an optional follow-up activity at the end of each week for you to use as homework. If students submit to me privately, I provide feedback.
