  • Brøker
  • Ekvivalente brøker
  • Blandede tall

Beskrivelse

Bygg brøker av figurer og tall for å tjene opp stjerner i dette brøkspillet, eller gjør forskning i brøklaben. Utfordre seg selv på akkurat det nivået du vil. Prøv å samle masse stjerner!

Eksempel på læringsmål

  • Bygg likeverdige brøker ved å bruke tall og bilder
  • Sammenlign brøker som bruker tall og mønster
  • Gjenkjenn likeverdige forkortede og ikkeforkortede brøker
  • Merk: Bygg en brøk bygger videre på idéer fra simuleringene Brøk-intro og Brøk-matching, men kan også brukes alene.

Standards Alignment

Common Core - Math

1.G.A.3
Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares.
2.G.A.3
Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
3.G.A.2
Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.
3.NF.A.1
Understand 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.
