RightStart Math Level B 1st Edition

Content is fully covered

  • Benchmarks of 25, 50, and 100 – The abacus helps compare and order numbers to 100.
  • Place value – these benchmarks are very concrete because of Abacus/ also RS reinforces these when studying coins – money is related to abacus – 50 is very obvious on an abacus and these benchmarks are discussed frequently.
  • Decomposing two-digit numbers into 10s and 1s – Knows 37 as 3-ten 7. Knows traditional names ie 18 as eighteen as well as 1-ten 8. Can trade 10ones for 1 ten. Can trade 10 tens for 1 hundred. Can trade 10 hundreds for 1 thousand. Can read four-place numbers.

  • Fluency with math strategies for addition and subtraction (e.g., making or bridging 10, decomposing, identifying related doubles, adding on to find the difference) – math practice sheets and games are used with the intention of mastering the addition facts to 20.
  • Many strategies are taught and practiced until they are automatic, such as: Two fives strategy, adding 1 to a number, adding 2 to a number, adding 10 to a number, making 10 (adding 8’s and 9’s), sums equal to 11 (comparing to 10s), even-odd adding rule studied and practiced (lesson 82).

  • Estimating sums and differences to 100 – Part-whole circles are used frequently to “separate” numbers and to put them back together.
  • 50 + 35 = 80) – Mental computation of two 2-digit numbers is studied – “add the tens and then add the ones” – students practice this daily in Levels B and C. Additional strategies are taught and the student is asked to use the one they find the most useful. Once it is taught, the addition of two-digit numbers is practiced daily in the oral warm-up exercises.
  • Whole-class number talks – new computational strategies are always introduced by orally working through and solving a math problem

  • Lessons 1-7 requires the student to study quantity using sounds (taps) and actions. Student is frequently asked to study a pattern (20,30,40__/coloured tiles__/geoboard patterns) and continue it.

Content is fully covered

  • The Abacus, tally sticks, hundreds chart are all used to reinforce the change in quantity throughout the program. Discovering the pattern for finding evens/odds by coloring evens on a hundred chart/ coloring odds on another hundreds chart (lesson81).
  • Lesson 92 – greater than/less than/equals/unequal.

Content is partially covered:

  • RS Math begins by doing activities to investigate measuring with non-standard units (feet, objects like tiles etc). Discussion of appropriate units is discussed for measuring things of varying sizes (a bug compared to a room). Inches are used to measure perimeter. Metric system is taught starting in Level C.

  • Identifying 2D shapes as part of 3D objects – Quadrilaterals are studied and compared to other shapes (lesson 24 ff). Identifying squares and rectangles as special quadrilaterals. Building rectangles from smaller rectangles (lesson 26ff). Making rectangles and squares from tiles. Studying right triangles – and making other geometric shapes using right triangles. Studying parallelograms from right triangles. Congruent rectangles on geoboards and sorting. Vertex and diagonal studied by drawing diagonal lines in rectangles. Diagonals drawn in hexagons and pentagons. Experimenting with symmetry (tiles, numbers, letters, equations and on the geoboard – lines of symmetry in a square).

  • One-to-one correspondence – The term “data” is learned/bar graph constructed/line-plot graph created/reading information from graphs (lesson 106)

  • Counting simple mixed combinations of coins to 100 cents Pennies, nickels and dimes and quarters are studied in Level B. Students are expected to be able to determine the value of three coins. Making change is taught and practiced extensively.
