Mastering Basic Facts
1 Virtual Manipulatives
iTool for Counters
In this virtual manipulative, the teacher will add different amounts of objects to both top and bottom boxes on the board. The student with then add the object to find the answer. If correct, then the teacher can show family facts about the problems.
Building Houses Activity:
In this Virtual Manipulative, the students will build a house out of cuisenaire rods and will be asked the following questions:
1. How many bars did you use? On the house? On the roof? Add and compare them.
2. How do the lengths of the bars compare?Are they half as big; twice as big?
2 iPad Apps
Sushi Monster-Students feed the sushi monster two or three number that add to up the given sum.
Math Slide Addition- There will be different types of addition and subtraction problems that the student must answer like using dice or addition and subtraction equations. The student must choose the right answer and slide it up onto the screen.
Addition and Subtraction for Kids- Students will be read a math problem (ex. 2+2) on the game. It provides the number fish of in the problem if they need a visual to help count with. They will pop the bubble with the correct number in it.
Key Standards Supported
Operations And Algebraic Thinking
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
Fluently add and subtract within 20 using mental strategies.2 By end of Grade 2, know from memory all sums of two one-digit numbers.
Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.
