TRANSCRIPT
Items you will need for this mini unit:
• an assortment of 3D shapes including cylinders, cones, cubes,
spheres, rectangular prisms and triangular prisms, in all different
sizes. I personally prefer to use everyday objects from around the
classroom, rather than a plastic set of 3D shapes, but of course you
could use either.
• A mystery bag (even a dark pillow case would be fine).
• A small ramp (or objects to make a small ramp).
Lesson 1:
• Discuss each 3D shape with the class, using grade appropriate
language for both the shape and its features. Provide your students
with lots of opportunities to handle the shapes, so they can feel the
features of each shape.
• Use the shape cards and shape name cards to identify each shape,
and the word name corresponding to each shape.
• You can then use the cards, as a matching game in your maths
centres to review and reinforce these concepts. There are blank
cards included, in case you would like to use other 3D shapes.
• Following teacher modelling, discussion and hands-on investigation,
students to complete the 3D Shape and Features worksheet.
(There are two different levels of worksheet to choose from).
• CRAFT ACTIVITY – using poster paint, each child can choose a
selection of 3D shapes and use the different surfaces and features to
create a shape painting e.g. Robots, animals, houses etc. to display
in your classroom.

Lesson 2:
• Review the 3D shape names and features from Lesson 1, with your
class.
• Ensure that your mystery bag contains enough 3D shapes so each
student will be able to have one shape each.
• One at a time, have a student come to the mystery bag. Without
looking, they place their hand inside and choose a 3D shape. They
are not to remove the shape from the mystery bag at this point,
but should hold onto it with their hand inside the mystery bag. The
student then has to describe their mystery 3D shape to the class.
The student can then choose peers to volunteer what they think the
mystery 3D shape is. Once it has been correctly identified, the
student then places the 3D shape into its correct category pile.
• It is now the next student's turn. Continue until all students have
had a turn. You can offer as much or as little assistance as is
required, for each student to be able to identify and describe their
mystery 3D shape, using its features.
• Students can complete the Mystery Bag 3D Shape Worksheet. I
have included 3D shape sheets for you to cut out. They can then
paste their 3D shape onto their worksheets.
• Students can complete the Mystery Bag 3D Shape Activity. With
this activity, each child secretly chooses a 3D shape. They write the
name of their chosen 3D shape onto the space provided on Activity
Sheet A. They then write clues as to their chosen shape's identity,
suing its features as the clues, onto the spaces provided on Activity
Sheet B. They then paste only the top section of Activity Sheet B
onto the allocated space on Activity Sheet A. Display these on a
bulletin board in your classroom and let the fun begin, with the
class trying to correctly identify each mystery bag 3D shape, based
on the clues!!

Lesson 3:
• Use a pre-built ramp, or construct a ramp at the front of the class.
• Each student chooses a 3-D shape and completes the first section of
the 3D Shape Action Worksheet.
• Each student places their 3-D shape onto the ramp and tests their
prediction, to see if their chosen 3D shape slides, rolls or can do
both.
• Encourage and guide a discussion about why certain features allow
some shapes to roll, some to slide and some to be able to do both.
Encourage the children to try all the different surfaces on each
shape, on the ramp, for themselves.
• Students then complete the rest of the worksheet.
• Use the Roll / Slide cards and the 3D shape cards from Lesson 1, to
play a matching game.
• Art activity ~ Students can create artworks with the action of the 3D
shapes. E.g.: rolling spheres such as marbles or plastic balls covered
in paint, over art paper in a tray etc...
