Pick a skill to light what it rests on.

Algebraic reasoning

  1. 1.5.F rests on 1.5.E an unknown is findable once the equal sign means both sides come to the same value
  2. 1.5.B leans on 1.5.A counting in twos and fives is its own sequence, and reciting every number in between makes it feel familiar
  3. 1.2.D rests on 1.5.A from another strand naming a number greater than 87 is reciting forward from it and stopping wherever you like
  4. 1.5.D rests on 1.3.B from another strand the number sentence for a story comes after the story is solvable with objects
  5. 1.4.C rests on 1.5.B from another strand counting a row of nickels is skip counting with coins in place of objects

Data analysis

  1. 1.8.B rests on 1.8.A drawing a graph comes after the data is sorted into categories
  2. 1.8.C leans on 1.8.B having drawn the bars is a fast way to learn what a reader is meant to take off them

Geometry and measurement

  1. 1.6.H rests on 1.6.G telling a real half from a near one comes after cutting fair shares by hand
  2. 1.6.B rests on 1.6.A telling which attributes define a shape comes out of having sorted by attribute
  3. 1.6.D leans on 1.6.B the formal names sit better once attributes are sorted, though children name shapes long earlier
  4. 1.7.C rests on 1.7.B comparing two unit sizes works on a length that is already a count of same-size units
  5. 1.7.D rests on 1.7.B a length said as a number and a unit takes the unit as the thing being counted

Number and operations

  1. 1.2.C rests on 1.2.B expanded form writes down the hundreds, tens and ones the number was built out of
  2. 1.2.E rests on 1.2.B comparing by place value works on a number that already comes apart into tens and ones
  3. 1.2.F rests on 1.2.E putting a set in order is comparing two of them, over and over
  4. 1.2.G rests on 1.2.E the symbol is shorthand for a comparison already made in words
  5. 1.3.D rests on 1.3.C making ten as a strategy takes a ten built out of parts as given
  6. 1.3.A leans on 1.2.B forty and seven making forty-seven leans on tens and ones, and just as often is how tens and ones get built
  7. 1.3.C leans on 1.2.A composing ten leans on seeing a small arrangement without counting it one at a time
  8. 1.3.E leans on 1.3.D explaining why you took two off the eight leans on having chosen the move rather than been handed it
  9. 1.3.F rests on 1.3.B writing a situation for a number sentence is the word-problem work run the other way
  10. 1.4.C rests on 1.4.A counting a handful takes each coin already having a known value
  11. 1.2.D rests on 1.5.A from another strand naming a number greater than 87 is reciting forward from it and stopping wherever you like
  12. 1.5.D rests on 1.3.B from another strand the number sentence for a story comes after the story is solvable with objects
  13. 1.4.C rests on 1.5.B from another strand counting a row of nickels is skip counting with coins in place of objects

Personal financial literacy

  1. 1.9.B leans on 1.9.A spending income leans on income having a name
