Multiply using the Partial Product and the Lattice Method
In my experience, especially as a teacher of students with
special needs, most students choose the lattice method to perform
multiplication problems containing numbers with two or more
digits.
I believe this option truly lets the student take the number in
smaller pieces and makes the operation more manageable for
them.

Help Me!Multiplying two digit and three numbers can be a scary
proposition for most children. By using either the partial product
method or the lattice method it allows students to take a more
organized, step by step approach!
Either of these methods will ease the students apprehension and
the best part is, students can choose the one they feel most
comfortable with.
Lets begin with the partial products method.
Lets multiply

5By breaking down the numbers you are multiplying by place value
the numbers become easier to manage. Then students can think in
terms of multiplying using base 10 strategies.Students can then
make an easier calculation.
Once you have multiplied each number, its time to add the
products. 1,350 + 225
1,350 + 225= 1,575Next you simply add the sums together and your
answer is 1,575!

then simply a matter of adding diagonally!5751,Winter
