● This portable ELA quizzes kids on addition, subtraction, multiplication, or division and works as a full-function calculator with the switch of a button.
● Problems are displayed on the LCD screen with eight skill levels as well as lights and sounds for instant feedback.
● Mute button for silent play.
● Requires two “AAA” batteries (not included).
● Grade 1 and up.
● CCSS Product Alignment 1.OA.3 Apply properties of operations as strategies to add and subtract.
● Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known.
● (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12.
● (Associative property of addition.) 1.OA.6 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).
● 1.OA.8 Determine the unknown whole number in an addition or subtraction equation relating three whole numbers.
● For example, determine the unknown number that makes the equation true in each of the equations 8 + ?
● = 11, 5 = _ - 3, 6 + 6 = _.
● 2.OA.2 Fluently add and subtract within 20 using mental strategies.
● By end of Grade 2, know from memory all sums of two one-digit numbers.
● 2.NBT.5 Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
● 2.NBT.6 Add up to four two-digit numbers using strategies based on place value and properties of operations.
● 3.OA.1 Interpret products of whole numbers, e.g., interpret 5 x 7 as the total number of objects in 5 groups of 7 objects each.
● For example, describe a context in which a total number of objects can be expressed as 5 x 7.
● 3.OA.2 Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each.
● For example, describe a context in which a number of shares or a number of groups can be expressed as 56 ÷ 8.
● 3.OA.4 Determine the unknown whole number in a multiplication or division equation relating three whole numbers.
● For example, determine the unknown number that makes the equation true in each of the equations 8 x ?
● = 48, 5 = _ ÷ 3, 6 x 6 = ?
● 3.NBT.2 Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
● 3.NBT.3 Multiply one-digit whole numbers by multiples of 10 in the range 10-90 (e.g., 9 x 80, 5 x 60) using strategies based on place value and properties of operations.
● 4.OA.1 Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 x 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5.
● Represent verbal statements of multiplicative comparisons as multiplication equations.
● 4.NBT.5 Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations.
● Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
● 4.NBT.6 Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division.
● Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
● 5.NBT.5 Fluently multiply multi-digit whole numbers using the standard algorithm.
● 5.NBT.6 Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division.
● Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
