Math Trailblazers è Fourth Grade Math Trailblazers is...
based on the belief that mathematics is best learned in
real-world contexts that make sense to children. Lessons
are grounded in everyday situations. A fundamental
principle is that mathematical ideas are internalized
through active involvement in solving real problems.
Strategies for assisting your
child...
Establish a homework routine
including a consistent time and place.
Keep it short and make it fun!
Ask questions that enable you to find
out what your child really
understands:
•Tell me how you did this.
•Explain your reasoning.
•How else could you do this?
•What would happen if...?
•
*Encourage independence.

End of Grade 4 Common Core Learning Outcomes Overview...
- Fluently add and subtract multi-digit whole numbers
using the standard algorithm
- Multiply a whole number of up to four digits by a
one digit whole number, and multiply two two-digit
numbers using strategies based on place value
- Find all factor pairs for a whole number in the range
1-100
- Round multi-digit whole numbers to any place
- Apply the area and perimeter formula for rectangles
- Measure angles in whole number degrees
-Classify shapes by their lines and angles
-
- Find whole number quotients and remainders with
up to four-digit dividends and one-digit divisors
- Compare two fractions with different numerators
and different denominators
- Add and subtract mixed numbers with like
denominators
- Solve word problems involving multiplication of a
fraction by a whole number
- Compare two decimals to hundredths by reasoning
about their size.
Math Trailblazers in Fourth Grade Key Vocabulary *Multiple: Any number that is
the product of a given
number. 18 is a multiple of
3 since 3 x 6 = 18.
*Prime Number: Any number,
which is divisible only by 1
and itself, such as 3 and 5.
*Factor Pair (Pairs of Factors): Two whole
number factors. A number may have
more than one factor pair. e.g. The
factor pairs for 24 are: 1 and 24, 2
and 12, 3 and 8, and 4 and 6.
*All Partials Method: A method of writing
out all of the partial products while
multiplying. Partial product
algorithm; e.g., 7 x 23; 7 x 20 = 140;
7 x 3 = 21; 140 + 21= 161
On-going skills to practice at home...
Look for “word problems” in real life. Some 4th grade
examples might include:
* Ask your child to compare numbers using phrases like
“times as much.” For example, if the family cat weighs 8
lbs. and the family dog weighs 56 lbs., how many times as much does the
dog weigh?
* Ask your child to help you compare fractional amounts — for example,
if one recipe calls for 2/3 of a cup of oil, but another recipe calls for 3/4 of
a cup of oil, which recipe calls for more oil? (In 5th grade, your child will
learn ways to determine just how much more oil.)
