Masharti ya awali ya lazima 2 (hadi chini kabisa)

Utajifunza

  • Compare and order objects by length, directly and by using a third object.
  • Measure lengths by laying copies of a unit end to end without gaps or overlaps, and then with a ruler.
  • Tell and write time to the hour and half hour on analogue and digital clocks.

Fasili

  • A unit is a fixed amount used for measuring, such as a centimetre or the length of a paper clip.
  • The length of an object is the number of units that fit along it end to end.

Nadharia

  • Measuring the same length with a smaller unit gives a larger number.
  • If A is longer than B and B is longer than C, then A is longer than C.

Mawazo potofu ya kawaida

  • Starting to measure from 1 on a ruler instead of from 0.
  • Leaving gaps or overlaps between units.
  • Thinking a string becomes shorter when it is bent.
