One of the concepts to learn next in Spanish is numbers.
The easiest way to start is to have students repeat the numbers after you.....uno, dos, tres, cuatro, cinco, seis, siete, ocho, nueve, diez.
Something fun to do is have one student say uno, another student says dos, the next one says tres and so on. The students have to be alert and ready to say whatever number is next.
Have students stand in a line, but have them change the order so that they can practice saying all numbers that they need to practice that day or class meeting.
Another way to practice is for the teacher to say a number in English and the students can say the equivalent number in Spanish. The teacher can also use a soft ball to throw at a student. She/he can say the number in English and the student can say the same number in Spanish.
It's also a good idea to have a number line with large numbers. Use a yard stick and point to different numbers, and the students can call out the correct number in Spanish.
Students can also recite the numbers in order individually in front of the class or whisper it to their teacher so that teacher can assess mastery.
This lesson has several of the necessary handouts to help students learn the numbers in Spanish.
