About my Products:
While the PARCC assesses many of the mathematical practice standards, I aim to create many problems and activities that require students to apply the skills outlined in the performance level descriptors. I believe that the more students are exposed to such type
Here is the problem most students have with multiplication, division, and multi-step word problems: They see the word “groups” and guess multiplication – but then see “gives away” and switch to subtraction instead of staying with the operation the problem actually demands. They solve Step 1 of a two-step problem and stop. They write the answer before they write the equation, which costs them the Setup point on the constructed response every single time. And when they hit a fact family question,
Here is the problem most students have with fractions: They draw a rectangle, cut it into 3 parts that are not equal, shade one, and call it 1/3. They place a fraction on a number line by counting the tick marks instead of the spaces – and land in the wrong spot every time. They say 3/8 is greater than 3/4 because 8 is greater than 4. And when they see 4/4 on a multiple select item, they skip it because “that’s just 1, not a fraction.” These are not random mistakes. They are the exact traps buil
