Mathematics Summer Practice

To help students strengthen and maintain their mathematical skills over the summer, the Mathematics Department has provided access to practice activities through DeltaMath.

Students may join the class using the code 2L3B-C759.

If you do not already have a DeltaMath account, you can create a free account using your school Google Account.

Once enrolled, you will have access to assignments and practice opportunities in a variety of courses, including:

• Algebra I

• Geometry

• Algebra II

• Intermediate Algebra

• Precalculus (as available)

• Calculus (as available)

Students are encouraged to work through any content that matches their current skill level or the course they will take next year. Regular practice over the summer is one of the best ways to retain mathematical knowledge and begin the new school year with confidence.

The Mathematics Department will continue adding assignments throughout the summer, so students are encouraged to check the site periodically for additional practice opportunities.

We encourage all students to take advantage of this excellent resource and to spend time strengthening the problem-solving skills that are essential for success in mathematics and beyond.

IB MATH SENIORS

1. Read Ellen’s IA handout. This contains a good description of the IA requirements and the rubric for the IA. There is also an important list of “no” topics The document was originally made for a different school, so ignore those parts of the handout.

2. Read at least two of the old IA papers found in the following drive:

https://drive.google.com/drive/folders/11x3ew-fn1A_gO7kI9-8xhI5iMvvKO97c?usp=drive_link

For each of those papers, summarize the paper, including at least 2-3 sentences about each of the following:

1. Describe what real world question the paper was asking

2. Describe what mathematics was used to analyze the question. Is this a bit of math you are currently familiar with?

3. What was your favorite aspect of the paper? Did you learn something new from it?

4. State at least one mistake or issue you found in the paper. Some examples might include missing axes on graphs, missing units, missing or inappropriate citations, or gaps in communication. 

Now grade the paper according to the rubric in the handout. Give at least a 1-2 sentence description of why you gave each grade in each category. For reference, a 10/20 is considered an ok score, a 5/20 is a poor score, and a 15/20 is a great score. This rubric does not fit the typical 90% A, 80% B, 70% C scoring you are used to!

Before leaving for summer, students in Dr. Steele’s and Mr. Hutcheson’s classes already ran through an activity for how to select an IA topic. If you have a topic idea,
