Cuisenaire Rods Fractions
Cuisenaire Rods Fractions. Here i introduced the white rod. Find a rod pair in which 1 rod is a third as long as another rod.
Grade 5 (1) students will visually see and manipulate fractions with cuisenaire rods staircase to develop concept and fractional relationships. Let students experiment with the cuisenaire rods for a few minutes. • record your findings in 2 ways.
We Then Determined The Red Rod To Be 2/7, The Purple To Be.
We noticed that white divides evenly into the black rod 7 times. Let students predict and then measure. Each colour rod is worth a different value.
In The Early 1950S, Caleb Gattegno Popularised This Set Of Coloured Number Rods.
If 1 white is 1/7, then 2 white rods is 2/7, and 3 white rods are 3/7. If red represents 1, show me 2 of ½ and ½ of 2. Cuisenaire rods also make effective models for decimals and fractions.

Cuisenaire rods are useful for students to build their number sense as the rods allow for easy comparison between each length. Pupils are set a range of challenges to create fractions with their cuisenaire rods. The value of this product is between the two factors, unless one of the factors is equal to one;
• Record Your Findings In 2 Ways.
Grade 5 (1) students will visually see and manipulate fractions with cuisenaire rods staircase to develop concept and fractional relationships. Measure the table in thirds of the light green rod. Explain why the fractions are equivalent, e.g., by using a visual fraction model.
Model Solutions To The Fraction Problems Given By Stacking And Connecting Your Virtual Manipulatives.
This is a nice task to try with years 7 to draw out prior knowledge and misconceptions. Here are 21 activities for cuisenaire rods, the set of 10 colored rods with each rod 1 unit longer than the previouos one. They can be used for a vast array of mathematical ideas, from counting to the four operations to fractions.
