Questimate! - Pro is a wonderful app to engage kids in solo, small-group, or classroom-wide estimation math practice. If you're using this as a classroom-wide lesson, be sure to work the problem through each available step -- from hints to full math explanation -- to get kids thinking about all the different components that go into an educated estimation. After playing Questimate! - Pro for a while, encourage kids to develop their own real-world estimation problems with items brought from home that are small enough to use in the classroom.Continue reading Show less
Questimate! - Pro is a remarkable math estimation game that puts kids in charge of making word problems with just enough guidance to keep the problems relevant and challenging. This app exposes kids to estimating real-world items in unique ways that focus on how math -- not just guessing -- can be used to estimate. From how many bread loaves equal the length of the average couch to how far a hippo can run in a minute, kids get to choose from various topics with types of estimation (length, speed, height, and more) via a fill-in-the-blank template with real-world options provided by the app.
If kids correctly answer the question "How many bars of soap would be as long as a yoga mat?" they earn points, hints, and power-ups to add some twists to gameplay. Kids can play solo, as a pass-and-play game with an in-person classmate, or via Apple's Game Center. Teachers can sign up for a paid account to gain access to a teacher dashboard. They can enter a class roster and track individual student progress. For example, teachers can track a student's mastery of a particular skill such as estimation by viewing that student's progress chart. The process for signing up involves additional costs after a 60-day free trial. Teachers must provide an email address and basic school information, and then they have to download another app to gain access to the progress tracker. Overall, Questimate! - Pro is a major winner for engaging kids in the art of estimation.Continue reading Show less
Learning is built into Questimate! - Pro's question-formation process, as well as in estimating the answers. The game's format makes the process fun and very sticky. It offers in-depth explanations in the "Really?!" section that include detailed photo- and equations-style explanations. Gameplay via the Pass & Play option adds collaborative learning, too. As students create the questions and then attempt to estimate the answers, kids must recall information they know about these objects and apply math, logical reasoning, comparing, and their own critical-thinking skills. As they do so, they learn about part-whole relationships and the art of estimation. And if teachers sign up for an account, the Teacher Dashboard can provide basic but useful information about individual student progress and mastery of skills.Continue reading Show less
Key Standards Supported
Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
Measurement And Data
Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).
Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l).6 Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.7
Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two- column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), ...
Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.
Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real world problems.
Recognize volume as an attribute of solid figures and understand concepts of volume measurement.
Measure volumes by counting unit cubes, using cubic cm, cubic in, cubic ft, and improvised units.
Number And Operations In Base Ten
Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.
Compare two decimals to thousandths based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
Number And Operations—Fractions
Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual model.
