Day 129: Area of Triangles / Topic Ten Posttest / Pythagorean Theorem

Today in Math 6, students in 1 and 3° used their knowledge from yesterday to provide a base for the lesson on area of triangles.  Once students were able to use intuition to uncover the formula for the area of triangle, Mr. Giomini stretched the skill by giving the students the area and one dimension to uncover the missing base or height of the given triangle.   

In 2°, Math 6 students were administered the Topic Ten: Unit Rate - Ratios posttest.  

During 7 °, students in Math 6+ worked with uncovering the intuition behind the formula for area of triangles. Once that was mastered, Mr. Giomini introduced students to The Pythagorean Theorem. This is an 8th grade indicator that we will be introducing and working with for the next two to three days.

  

Today's Learning Targets: The student will be able to...

• use ratio reasoning to convert measurement units. (2°)
• manipulate and transform units appropriately when multiplying and dividing quantities. (2°)
• find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes. (1, 3, & 7°)
• apply the Pythagorean Theorem to determine unknown side lengths in right triangles. (7°)

For Evening Practice, the student is expected to...

• Complete page 668 and Reteach 13.2.
• Have 75% of 6th Grade Khan Skills mastered by March 23rd.
• 2° -
• Catch up on Khan.
• Have 75% of 6th Grade Khan Skills mastered by March 23rd.
• 7° - 
• Complete page 668 and Reteach 13.2.
• Have 50% of 7th Grade Khan Skills mastered by March 23rd.
• All Classes: Complete at least 10 minutes of work on Khan Academy to help review old content, practice new material, or front-load future concepts.
