2nd Grade Splash Math Education Learning Workbook could be a great choice for the whole class to practice end-of-the-week math skills and to review previous concepts. If the class has been learning money skills, each student can have plastic (or real) coins to identify or count along with the question on the screen, ensuring the whole class is participating. Extend the geometry "chapter" by asking kids to replicate drawing "a shape with 5 (or other number) vertices" and having them identify it, or determine what shape would be made of 3 (or more) lines.Continue reading Show less
2nd Grade Splash Math Education Learning Workbook is designed to be an entertaining way to let kids practice Common Core State Standards-aligned second-grade math skills. Skills addressed include Place Value, Counting and Number Patterns, One Digit Addition, Two Digit Addition, Three Digit Addition, One Digit Subtraction, Two Digit Subtraction, Three Digit Subtraction, Time, Measurements, Money, Geometry, and Graphs. Teachers can set up accounts for each child in the class and, within those, choose difficulty level as well as skills that are to be practiced from the above categories. The robust controls enable teachers to customize the learning experience for students who may have learning disabilities or may be struggling with math.
Kids work with problem sets of math skills for the second-grade level, earning little origami fish "friends" for their "aquariums" as they go. As they earn fish, they can play within the aquarium setting, making the fish dance or chase each other, feeding the fish, or dropping anvils on crabs. The app includes on-screen notifications of progress in each area as kids work through the game; teachers can retrieve this information directly from the app in the Parent section, or can opt to receive email notifications of a child’s progress.
Graphics and sound are whimsical and colorful without being distracting, and on-screen instructions are clear and helpfully visual (for example, kids learn to click and drag via an animated instruction). The range of topics is great, too: This is much more than a drill-and-kill math review app. Instead, Splash Math dives deep into critical topics like number sense and explores them with depth. The origami-style fish are cute, and kids will enjoy solving math problems to earn fish for their aquariums. Parents can choose whether or not questions are read to kids (in a digitized voice), which could be helpful for kids who are pre-readers or who have reading difficulties.
The 13 chapters of math topics are well-structured and allow flexibility to target a single skill or tackle a range of topics. The biggest drawback is probably the feedback: The aquarium reward system is completely disconnected from the learning process. It would be even better if kids got more detailed feedback and more relevant milestones that helped them track their progress more meaningfully.
Key Standards Supported
Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces.5 Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.
Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.
Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
Measurement And Data
Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.
Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.
Estimate lengths using units of inches, feet, centimeters, and meters.
Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.
Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, e.g., by using drawings (such as drawings of rulers) and equations with a symbol for the unknown number to represent the problem.
Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, ..., and represent whole-number sums and differences within 100 on a number line diagram.
Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put- together, take-apart, and compare problems4 using information presented in a bar graph.
Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object. Show the measurements by making a line plot, where the horizontal scale is marked off in whole-number units.
Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.
Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately. Example: If you have 2 dimes and 3 pennies, how many cents do you have?
Number And Operations In Base Ten
Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:
Count within 1000; skip-count by 5s, 10s, and 100s.
Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.
Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.
Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
Add up to four two-digit numbers using strategies based on place value and properties of operations.
Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three- digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.
Mentally add 10 or 100 to a given number 100–900, and mentally subtract 10 or 100 from a given number 100–900.
Explain why addition and subtraction strategies work, using place value and the properties of operations.3
Operations And Algebraic Thinking
Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.2
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.
Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.
Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.
