Kara Root

These are horizontal flashcards that contain the fact families 0 - 5 for both addition and subtraction. They are written both ways on cards ( 1 + 4 and 4 + 1) There is also a monitoring sheet that students or teachers can fill out when they master the fact. We say that a student has mastered the fact when they can give the answer immediately upon seeing the card (within 5 seconds). My students have to prove that they know them on 2 different days before they get to color their chart in. They ca

These place value strips can be printed off and used in front of the classroom or for a group of students. These help the students see that 1,289 is really 1,000 + 200 + 80 + 9. I print each place value on a different color of cardstock so that they can easily see the different place values. Check out the preview to see a picture of the one I printed for use in 4th grade.

In this activity, students will roll two dice and record the sum. They then need to make a frequency table, histogram and find the probability of each sum. They are asked question throughout the activity to lead them. The second part is to then find the probability as a class for each of the sums. At the end, they need to figure out the theoretical probability and compare to their probability. I have used this activity with small and large groups. I like to tie in to the fact that the mo

In this experiment, the students learn about the basics of probability and what happens depending on the sample size. The students predict based on a sample what is in their bag and then find out if the are correct. Then using the actual data the students calculate probabilities based on individual, group and class results. They graph this information as well. There are questions along with this activity that ask why and get at their thinking. In the end they compare the class results wit

These are horizontal flashcards that contain the fact families 0 - 12. There is also a monitoring sheet (check out the preview) that students or teachers can fill out once a week when they master their facts. We say that a student has mastered the fact when they can give the answer immediately upon seeing the card (within 3 seconds). We print them off (flip short side so they print correctly back to back), laminate them, and place each set in a ziplock bag. The first time, we start at the b
