One tool I use to provide productive diversity in the classroom is Imagine Learning. Below is a video to help you understand what Imagine Learning does for students. 

Imagine Learning is an adaptive program that provides students with support in a variety of subjects. Below is an image of their programs. 

In my classroom, the main programs we use are Imagine: Language & Literacy and Imagine: Español. Working in Dual Language classroom can be challenging with regards to finding high-quality resources in both English and Spanish. We often find that there is an abundance of English resources, many that are free, and of excellent quality. Students are able to practice these skills virtually anywhere as long as they have their device. My district is currently 1:1 with Chromebooks (3-8) and iPads (K-2). With the goal of our program being that students are biliterate and bilingual by the end of the program, we often find that students are more proficient in English than they are in Spanish due to the number of quality resources available to students. 

Imagine Learning is a program that has a variety of platforms including English, Spanish, and math programs. Our school specifically uses their English and Spanish programs. The program starts by having the student take a pretest. This pretest will then place the students at a certain grade level. Students will then begin by going through a series of lessons. Students work on building academic vocabulary and skills through games and books. Students are also asked to record themselves reading and listen to it and check for their own accuracy. Once students master a concept they move on. If students are struggling after being taught a variety of time, it will alert the teacher to focus in on specific skills. 

This program has helped my class build English and/or Spanish skills. Students can practice at home and will have second language development support which is often hard to get. Ultimately, this puts both languages at the same status and each child in my class can get the support they need regardless of their native language and level of support at home.
