Dyben Into Math

The Activity Students will determine from three math statements which two are true and which one is the “lie.” Each lie has a common mistake from order of operations, radicals, expanding binomials, and more. After the students determine which statement is false, they will justify their answer by describing the mistake that was made. Altogether this activity takes 15-20 minutes. To turn it into a whole lesson (and to make it more fun!), before the students do the activity, have the students wri

Meets: CCSS HSN-CN.A.1 Know there is a complex number i such that i2 = –1, and every complex number has the form a + bi with a and b real. CCSS HSN-CN.A.2 Use the relation i2 = –1 and the commutative, associative, and distributive properties to add, subtract, and multiply complex numbers CCSS HSN-CN.A.3 Find the conjugate of a complex number; use conjugates to find moduli and quotients of complex numbers. This packet includes guided notes and skeleton notes on the complex numbers and powers of

This activity guides students through an investigation of function transformations in order to construct knowledge about translations, vertical stretch/compresses, and reflections. It also has one practice problem that puts their knowledge to the test. Students must have prior knowledge of quadratic, cubic, square root, and absolute value parent functions. They will also need access to graphiing calculators or graphing software such as Desmos, Geogebra, etc. This activity will take approxima

This activity typically takes 30-40 minutes and is the main activity on the first day of school in my classroom! Stop boring them with class policies and syllabi and engage them in creative thinking and collaboration on the first day. The students will find it somewhat challenging and definitely engaging. In this fun first week of school activity, students will get to know their teammates and their classmates by discovering what they have in common and representing what they've discovered on
