This is a growing collection of resources that I’ve used/wanted to use in intervention classes for 6th graders to support them with Illustrative Mathematic’s first unit: Area and Surface Area.

Area and Perimeter of Rectangles (background knowledge)

Number Search In this warm up activity, kids find the area of other shapes (5-10 minutes tops!)

Perimeter and Area of RectanglesIn this short task, kids reason about the perimeter and area of 5 different rectangles.

Leveled Practice: Area of Rectangles Cut up and chunk into the separate levels. Give each partnership one level at a time to work on. From BossMath

Names of 2D Polygons (background knowledge)

Desmos Triangle Polygraph A “Guess Who?” game to elicit and practice triangle vocabulary.

Zukei Puzzles One of many puzzles  shared on mathequalslove. This one helps kids build familiarity with the following vocabulary: square, rectangle, isosceles triangle, isosceles right triangle, right triangle, rhombus, trapezoid, parallelogram. The task is to connect some of the provided dots to form the specified shape. The dots must lie on the shape’s vertices. Even more Zukei puzzles at BuildingMathematicians

Area of Polygons on a Grid (6.G.A.1)

Desmos: Area of Triangles on a Geoboard  Kids can practice finding the area of triangles on a grid by reasoning about composing, decomposing, and rearranging.

Sankaku Puzzles Kids need to connect 3 dots to form a triangle with the specified area.

Make Art and Find the Area Give kids a piece of graph paper and ask them to create a work of art. Give them some requirements, such as needs to include 3 triangles etc. Then they need to find the area of their creation.  Can also ask them to write their names in block letters: Source

Area of Polygons without the Grid (6.G.A.1)

Increasingly Difficult Scaffolded Practice:  Includes problems both and and off the grid:  Set 1  answers Set 2 answers	Graphic Organizer for Formulas Could definitely be improved…! Practice Identifying the Base and Height! Created by Jodi Tucker and shared on the Open Up Grade 6 Facebook Group	Leveled Practice: Area of Compound Shapes  Chop up into levels to chunk and give kids one half-sheet to work on at a time.
Enclosing and Subtracting Somewhat challenging practice problems that lend themselves to the strategy of enclosing and subtracting.	Leveled Practice: Area of Triangles Research has shown that learning to identify the base and height takes a lot of practice. These exercises offer a great opportunity to have kids practice highlighting a base and height pair for each triangle and labeling them b and h.	Same Surface Deep Difference: Four Triangles

Surface Area 6.G.A.4

Make 3D Shapes Give kids printed copies of nets of polyhedra. Kids can:-Predict what they will look like-Figure out what to measure with a ruler, label the net, and calculate the surface area-Cut them out and fold them up Alternatively, you could make them in advance, have kids try to sketch the nets, and then unfold the figures to reveal the net.

Open Middle Challenges Kids reason about what the dimensions of a rectangular prism could be. May benefit from having access to unifix cubes and/or a sketch of a rectangular prism’s net.

Does it Make a Cube? Kids predict whether each net can make a cube or not and then see an animation of the net folding up.
