Operations and Algebraic Thinking: Understand and apply properties of operations and the relationship between addition and subtraction, and work with addition and subtraction equations.
(CCSS.1.OA.B.3, CCSS.1.OA.D.7, CCSS.1.OA.D.8)
Grade 1 students have a misconception of the meaning of the equal sign. Since students have an operational view of the equal sign, they believe the equal sign means to write the total, the answer or the result of the operation. It is imperative for students to develop a strong understanding of the meaning of the equal sign in order to solve equations and real-world problems. More so, understanding the relationship of properties helps students understand how numbers are related. On-line educational resources provide an optimum way to enhance classroom instruction and for all students to develop a conceptual understanding of the topic.

Operations and Algebraic Thinking: Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.
(CCSS.K.OA.A.1, CCSS.K.OA.A.2, CCSS.K.OA.A.3, CCSS.K.OA.A.5)
Kindergarten students struggle with the concept of addition (putting together) and subtraction (taking apart) and how to properly solve word problems involving these two operations. A strong foundation of the operations of addition and subtraction is essential in Kindergarten. Achieving a number sense at an early age allows students to adequately grasp more complex mathematical concepts at each subsequent grade level. On-line educational resources provide an optimum way to enhance classroom instruction and for all students to develop a conceptual understanding of the topic.

This website is verified according to the criteria for evaluating web resources. The evidence includes the following: the site is associated with a reputable educational institution, it matches the topic of interest, it does not reflect a biased point of view, it is free of errors, it is frequently revised, and it's accessible by all learners. With this website, students will practice addition and subtraction using the interactive activity, How Many Under the Shell? On the set-up screen, students will select the random button, allowing access to solving random addition and subtraction problems up to 10. Students will either solve how many bubbles have been added under the shell or solve how many bubbles have been taken from under the shell, by inputting the solution on the keypad. Further, the teacher will advise struggling students to select a specific number on the keypad of the set-up screen, instead of the selecting the random button. This number would be equivalent to a sum or difference less than 10, based upon their individual mathematical ability. Students then select "+", "-", or "+ or -" based upon which operation needs to be practiced. Students can then progress to a sum or difference of 10, ultimately the random equations. Further, the confidence test would be an alternate assessment based on UDL used for this topic. Students would note each question with a confidence score of 1 (least) through 10 (most), based upon their certainty of correctly completing each word problem.
