This is a pre-assessment before a trigonometry unit. The assessment is basic trig ratios and solving for missing sides. The students rate their knowledge for each question.

This assessment is for criteria B and D geometry unit. The students research mosaics in the Islamic world. They share their findings and then make their own mosaic. The students will calculate area and perimeter of various quadrilaterals/triangles. A rubric is included.

This activity is practice making pie charts. The pie chart that is included has 100 marks to make it perfect for using percents to create pie charts. The last page is the students creating their own question and surveying the class to create their own pie chart. Students need to know how to convert between fractions, decimals and percents.

This is an inquiry activity into trapezoidal rule for the IB AI SL course. The students are given 2 functions(polynomial) and asked to find the area under the curve with the integral and then using the trapezoidal rule. I had the students cut out the trapezoids and glue them onto the original. They calculate with 2 different heights and compare their answers.

This is a constructions book that students use to compile geometric constructions. There are a few extra practice problems and many of the constructions require the students to list the steps they used. This usually takes a few days to teach, depending on how you present it. I have included points of concurrency.

This is an activity for reviewing number sense with MYP students. The students will calculate and compare the diving scores from the Paris 2024 Olympics. This involves adding and multiplying decimals. There are analysis questions at the end to get the students to think about the real life applications of mathematics.

The algebra cycle included equations, tables, graphs and stories. The students are given one of the 4 parts and need to complete the other 3 parts. I like to use this as group work and it's easy to differentiate for various levels.

This activity has practice making dilations with the parallel method. Then the students will work in groups to make a larger dilation.

This project uses desmos to create triangles with points of concurrency. There is practice and then a design project at the end. Rubrics are included.

This activity is used to help derive the distance and midpoint formulas. The students work through problems to help them create the formulas and understand where the terms in the formulas are coming from. This is an inquiry activity where the students use their ATL skills to problem solve and communicate their understanding.
