I just wanted you to know that I practice what I teach. We have a entering kindergartener in the house and I am beginning to work with her on subitizing numbers. 

 Subitizing means to instantly recognize a quantity without counting.
 These are the steps in my house to the second floor. I taped the number dots on the risers of the stairs.  As she walks upstairs, she says their value... 3,3,2,3,2 and so on.  I will change the cards to  larger number values as the posted numbers become too easy.  Since she will be in a Dual Language Class, next she will say the numbers in Spanish too.  In her class, math is taught in Spanish.

John Van de Walle discusses subitizing in his book, "Teaching Student-Centered Mathematics: Grades K-3."  You can print a copy of his blackline masters of the dot patterns that are smaller in size than shown in my photo. Just click here .

I always say-  break in down in learnable bits...
 with a spoonful of sugar.

Computer Research for Fourth Grade Common Core Math Standard 4.OA.3

Here is a research project that can be completed in the computer lab for:  Math Standard 4.OA.3

Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

Go to which shows the entire McDonald’s menu.

When you hover your mouse over a food item you can view it's  nutritional information.

 Students use this information to write a multistep math problem and it's solution.  Students print their problem, and then exchange problems with other students to solve.
