This is one of the first lesson’s
we did in our unit on

**FRACTIONS.**Students completed a pre-test and K-W-L chart on fractions the day before. To assess whether students were able to identify fractions represented in different ways, I decided to use a progressive brainstorm.
Students were placed into four
mixed-ability groups and each group was given the same colour marker. Each
group was given a poster with a fraction on it. They then had three minutes to
write everything they knew about that fraction on the poster. This activity is
also sometimes called a

**GRAFFITI ACTIVITY.**When the three minutes finished, the posters were moved to the next group and so on, until each group had a chance to write on each poster. We then shared our posters at the end of the lesson.
The progressive brainstorm strategy
works well for EAL students as they are working with their peers and are able
to see different ideas on the posters as they are moved around to the groups.
Hopefully the different images and visuals on the posters help them spur their
own ideas to put on the posters. This activity is great to activate student’s
prior knowledge of the topic.

Here are the posters from our
class. Remember that when we first started the activity, I had only written the
following onto the posters.

*one fifth (written out in words), 1/3 represented as a circle, 1/4 represented as a set, 3/4 written as a fraction*

From this activity, I was able to
learn a few things about the students’ knowledge of fractions. Firstly, most of
the students have not understood that each piece of the fraction needs to be an
equal part of the whole. Also, I learnt that the majority of students in the
class were able to recognise a common fraction based on a picture. This will
help lead my sequence of activity for the next few lessons on fractions.
