A study of the use of manipulatives in the assessment of mathematics instruction with ESL Hispanic students. Bilingual Research Journal, 22(2-4), 215-235. I'm including this reference and abstract because it seems like an ideal research article for our group. Unfortunately, the report is written in Spanish only.
Red Rangers are a generation cross from the popular Rhode Island Red & are also known as Columbian Blacktails. These pretty chestnut hen's adapt well to most set up's, especially as backgarden hen's, free-rangers and smallholdings.
In the hotter summer months, we raise Red Rangers. Our Red Rangers are a great alternative to the modern supermarket bird of today (Cornish Cross). The genetic stock is derived from US developed pedigree lines using old heritage breeds of chickens.
