Summary
|
|
| Pre
2.0a Fraction Problem Solving with Tiles PDF
|
Students
problem solve, build, record and explain the numbers of
different colored tiles in the rectangles.
|
Pre
2.0b Fractions and Algebra with Rods PDF
|
Students
examine
the fractional relationships using Cuisenaire rods.
They
record these relationships algebraically and explain their
equations
|
Pre
2.0c Fraction Problem Solving with Pattern Blocks
PDF |
Students
use
pattern blocks to model proper and improper fractions. They
assign different shape units as the “whole” and
then relate the different pattern blocks to that “whole.”
|
Pre
2.0d Assessment
|
Students
use fractions and algebraic representation to solve the assessment
question. |
| Pre
2.1a Tangram Fractions
Create
a Tangram
Tangram
story |
Students
create a square using tangram puzzle pieces, label each shape’s
area as a fractional part of the whole and then relate the
fraction values to the decimal values. (Access the link to
Create a Tangram if you wish students to create their own
and learn geometry and fractions in the process.) |
| Pre
2.1b Tangram Fraction Fun
PDF
|
Students
build different geometric shapes using specified numbers of
tangrams and write equations which add the fractional pieces. |
| Pre 2.2a Wholes and Parts |
This lesson provides a conceptual foundation for multiplication and division of fractions. Students divide whole bars into parts and circle the number of parts to represent the fractions (like multiplication). Then they represent the parts and figure out the whole bar(like division). |
Pre
2.1c Adding and Subtracting Fractions with fraction bars.
*Fraction
Bars Charts (7 pages)
*Bar
chart (seven on one page)
|
Students
create fraction strips using card stock and use the strips
to add and subtract fractions with like and unlike denominators.
They derive the common denominator concept.
*Access bar chart at left--see directions in lesson. |
| Pre
2.2 Multiplying Fractions with Area Models PDF |
Students
model
multiplication using area models. and discover the rule
for multiplying fractions.
|
| Pre
2.3 Modeling Division with Fractions PDF |
Students
relate division to factoring. Then they investigate fraction
division using fraction strips. |
Pre
2.4a Fraction Assessment
PDF
|
Students
must problem solve to prove their understanding of fractions. |
| Pre
2.4b Operating with Fractions Assessment PDF |
Students
must prove their understanding of operations on fractions. |
| Pre
2.5 Fractions, Decimals, Percents and Candy PDF |
Students
use candy and visual models to relate fractions, decimals
and percentages. |
Pre
2.6 Problem Solving with Fractions, Decimals, Percents
PDF
|
Students
consider fractions and percents asrelated to the number of
almonds in a candy bar. They also build rectangular areas
(using color tiles and graph paper) to visualize and find
a percentage of the whole and then the whole from the percentage.
|
Pre
2.7a Estimating with Fractions, Decimals, Percents
PDF
|
Students
order fractions and decimals based on size. They estimate
fractional quantities using fraction, decimal and percent
equivalents.

Questions |
Students
work in groups to find the common fraction/decimal/percentage
equivalents. They practice estimation using these equivalents.
|
Pre
2.9a Fractions, Decimals, Percents in Data
PDF
|
Students
use percentage reasoning to read pie graphs. Then they extend
their understanding by calculating percentages for specific
situations. |
Pre

Assessment:
If the Word Were a Village
Worksheet
|
Students
and teachers read If the World Were a Village. After
discussing questions which relate the book to their school,
city, or state, they work to solve percentage problems (see
worksheet) or they formulate their own questions to research,
solve, and present solutions for. |
