Mashup Math

18 episodes

Mashup Math is a free YouTube channel of short, colorful lessons that walk grades 3 through 6 students through one math skill at a time. Narrator Anthony Persico builds each idea from a picture before the rule: fraction bars, area-model boxes, unit cubes, and number lines make the reasoning visible. This vetted collection gathers the upper-elementary slice, including equivalent fractions, fraction arithmetic, decimals, multi-digit multiplication, the distributive property, order of operations, area and volume, using a protractor, line symmetry, bar graphs, line plots, and ratios. Each clip runs from two to twelve minutes, so a teacher can drop one into a math block, pause to work an example, and match it to a specific standard.

4.G.A.3Recognize a line of symmetry for a two-dimensional figure; identify line-symmetric figures and draw lines of symmetry.
4.MD.B.4Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8); solve problems involving addition and subtraction of fractions using the data.
4.MD.C.6Measure angles in whole-number degrees using a protractor; sketch angles of specified measure.
4.NBT.B.5Multiply 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.
4.NF.B.4Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.
4.NF.C.6Use decimal notation for fractions with denominators 10 or 100.
5.MD.B.2Make a line plot to display a data set of measurements in fractions of a unit; use operations on fractions to solve problems involving information presented in line plots.
5.MD.C.4Measure volumes by counting unit cubes, using cubic cm, cubic in, cubic ft, and improvised units.
5.MD.C.5Relate volume to the operations of multiplication and addition and solve real-world and mathematical problems involving volume.
5.NBT.A.3Read, write, and compare decimals to thousandths using base-ten numerals, number names, expanded form, and >, =, < symbols.
5.NF.A.1Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions with a common denominator.
5.NF.B.4Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.
5.OA.A.1Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.
