  • Ekvivalente brøkar
  • Blanda tal

Description

Bygg brøkar av figurar og tal for å tene opp stjerner i dette brøkspelet, eller gjer forsking i brøklaben. Utfordre seg sjølv på akkurat det nivået du vil. Prøv å samle masse stjerner!

Døme på læringsmål

  • Bygg likeverdige brøkar ved å bruke tal og bilete
  • Samanlikn brøkar som bruker tal og mønster
  • Identifiser likeverdige forkorta og ikkjeforkorta brøkar
  • Merk: Bygg ein brøk byggjer vidare på idéar frå simuleringane Brøk-intro og Brøk-matching, men kan også brukast aleine.

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.2
Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.
 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.
 3.NF.A.2
Understand a fraction as a number on the number line; represent fractions on a number line diagram.
 3.NF.A.2a
Represent a fraction 1/b on a number line diagram by defining the interval from 0 to 1 as the whole and partitioning it into b equal parts. Recognize that each part has size 1/b and that the endpoint of the part based at 0 locates the number 1/b on the number line.
