Didax Publishing, page 26. The probe will first be probing for the student’s ability to see part-whole number relationships. For each of the students I started off with the number 6 because it was a number in the middle. If a student is not able to master the number 5 the assessment will move backward to assess the number 4, if the student is able to show master of the number 6 then they will move up to the assessment of the number 7. Assessment: With Counters 1. First I have the child count out that many counters, I place the excess counters to the side. 2. Then I close my hand around the counters and confirm that he/she knows how many are hidden there. 3. Then I remove some and show them in the palm of my other hand. 4.

For division, teachers should help students identify and use different meanings of remainders to help the learners understand and apply different rules. As students become…

To complete this task, she had one teacher using cards that showed the number and an equal number of shapes (card 5 would have 5 stars). She gave each student 2 cards and asked them to either add or subtract the two numbers. She then would ask the students…

s: Translations are the process of moving around all of the coordinates that make up a shape. All the points move the same distance in the same direction. The transformation is isometric which means that it does not change in shape or sides. If the pre-image moves either right or up the coordination would be adding. If the pre-image moves either left or down the image would be subtraction. The picture to the right is an example of translation. The answer to the question at the bottom would be…
