***UPDATE:***
Due to the MAP testing taking longer than expected, our assessment on Opposites has been moved back. My goal is to have it completed on Wednesday. Also, I have decided to save the DMRQ1.2, and use it next week, since we were unable to do Monday and Tuesday's problems due to the MAP test. (So there will not be a DMR Q1.3.) We made it through week one! This week will begin with a quick review and an assessment that covers what we have been working on since Wednesday, opposite quantities combining to make zero. Ex: 5+5=0. Last week we used the Integer Game: a card game that creates a conceptual understanding of integer operations and serves as a powerful mental model students can rely on during the unit. .After the assessment (it's only 5 questions) students will begin taking their MAP test online that will help us place them in the proper RTI groups for PLT. We will then move on to modeling addition of integers on a number line. Students model this by using horizontal arrows; for example, an arrow for −2 is a horizontal arrow of length 2 pointing in the negative direction. We will recognize that the length of an arrow on the number line is the absolute value of the integer. We will add arrows (realizing that adding arrows is the same as combining numbers in the Integer Game). Given several arrows, students indicate the number that the arrows represent (the sum). Towards the end of the week we will think of addition of integers as putting together or counting up. For negative numbers “counting up” is actually counting down. The use of arrows to show the sum of two integers, 𝑝+𝑞, on a number line and to show that the sum is distance 𝑞 from 𝑝 to the right if 𝑞 is positive and to the left if 𝑞 is negative. We will continue to refer back to the Integer Game to reinforce their understanding of addition. I have attached the DMR and the Math Mania for the week! Comments are closed.
