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.
Our Red Ranger chicken is a heritage bird that is very different from the normal white Cornish Cross birds. It takes these birds several more weeks to get to the ideal market weight and this is what most feel sets them apart from the Cornish Cross birds. They make a very moist, flavorful product that you will enjoy.
