D. Independent Practice-
1. Teacher will pass out page 39 and have students color the monkeys.
(10 minutes) Let students know that the timer will be set for 10 minutes
and they have to be done at that time. Give a 2 minute warning to
let students know that time is about up. Students need to put crayons

8. Teacher Reflection-
|
MoStep- Goal 1
I understand the concept of teaching addition and subtraction at the
first grade level. Teaching math concepts using objects, pictures,
or symbols is a beginning math concept students need to learn to further
their learning in math. The teaching tools used is a fun way of learning
and bringing fun into the classroom is a way to get students to want
to learn. If students think learning can be fun they are more apt
to want to learn. |
