Khan Academy

22 episodes

Khan Academy is the free nonprofit learning resource teachers already trust, and these are its short elementary-math lessons. Sal Khan works one skill at a time on a digital whiteboard: naming and sorting shapes, splitting wholes into equal parts, building and comparing fractions on a number line, reading scaled bar graphs and line plots, classifying triangles and angles, drawing with a protractor, and converting customary units. Each clip runs a few minutes and lands on a single grade 2 through 4 standard, so you can drop one in to introduce a concept, reteach a small group, or send it home. Every video is vetted for classroom use.

3.NF.A.3Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
2.G.A.1Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces; identify triangles, quadrilaterals, pentagons, hexagons, and cubes.
3.NF.A.1Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
4.G.A.1Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines; identify these in two-dimensional figures.
4.G.A.2Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size; recognize right triangles.
2.G.A.3Partition circles and rectangles into two, three, or four equal shares; describe the shares using the words halves, thirds, half of, a third of, etc.

2.MD.C.8Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately.
3.G.A.2Partition shapes into parts with equal areas; express the area of each part as a unit fraction of the whole.
3.MD.B.3Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories; solve one- and two-step "how many more" and "how many less" problems.
3.NF.A.2Understand a fraction as a number on the number line; represent fractions on a number line diagram.
3.OA.D.9Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations.
4.MD.A.1Know relative sizes of measurement units within one system of units; express measurements in a larger unit in terms of a smaller unit.
4.MD.A.3Apply the area and perimeter formulas for rectangles in real-world and mathematical problems.
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.
