Number Sense and Numeration- Equivalent Fractions

Equivalent fractions are fractions that represent the same part of a whole or the same part of a set or object.  They have the same value.


Examples of equivalent fractions are:

1/2 is equivalent to 4/8.

1/3 is equivalent to 4/12.

You can practice matching equivalent fractions with Fraction Frenzy.  I also found a fun activity and game that will let you practice some more equivalent fractions.  I hope you enjoy them.

Understanding Matter

My grade 5 students began exploring the concept of matter.  Matter is anything that has mass and takes up space.  We learned the three states of matter: solids, liquids and gases.

Solids - keep their shape unless they are broken.  They do not change their shape and have strength because they are held tightly by particles.  The particles do not flow (move) however, they can jiggle (vibrate) and they keep their volume.

Liquids - do not keep their shape. Instead, they take on the shape of any container.  For example, water takes on the shape of the glass or cup that it is in. The particles in a liquid can flow (move) because they are arranged closely together and keep their volume.

Gases - has no shape, however, they can fill the container that they occupy.  The particles are separate and they can flow (move) quickly and fit into a smaller volume.

We will continue exploring and investigating the differences between the physical changes (reversible) and chemical changes (non-reversible).  However, if you would like to challenge yourself, do so by playing this solids, liquids and gases game.  Good Luck!

Geometric Properties

We investigated angle measures in triangle and learned the following:

ACUTE TRIANGLE

All angles are less than 90 degrees.

RIGHT TRIANGLE

Has a right angle (90 degrees).

OBTUSE TRIANGLE


Has an angle more than 90 degrees.



Can you identify and classify triangles by angles?  Test yourself.   You can also challenge yourself with this game- Triangle Sort.
