Responding to Parent Concerns
What about fact practice?
?
When are algorithms introduced?
Are students prepared for higher level mathematics?

Students will determine the color of cube “x”
given a prepared AB, AAB, or ABC cube train.
2
Activity:
Students make a building with
connecting cubes, given a certain
number of rooms per floor (ex: 3
rooms/floor). Then they determine
the total number of rooms in a
building with a certain number of
floors.
Second Grade

Students create a table to represent
the ratio of # of floors to # of rooms.

5 nights if they receive a different number of
marbles each night.
Students then write a rule to determine how
many marbles each of the 3 children will have
on any given night.

Students look at one set of
data represented in the form
of a table and compare it to
another set of data
represented in a graph.
• Which bike shop offers better
rates?
• What is the best way to
compare this data?
•What patterns can you find
and how can you use the
patterns to predict values not
included?

Tyrel and Dalia bought some pens and pencils. Tyrel
bought 4 pens and 5 pencils, which cost him $6.71. Dalia
bought 5 pens and 3 pencils, which cost her $7.12.
Let x = the cost of a pencil
y = the cost of a pen
4x + 5y = 6.71
5x + 3y = 7.12
