EnVision Topic 1 Samuelson

1. The following slides are my team’s version of
lesson plans for the math topic of study.
They are shared as suggestions ONLY…please
consider sharing your plans on the dropbox...
we’d love to see how other teachers are
using the program 
We use some of these slides during our lessons to
incorporate different math practices as we do number
talks to help our students practice on skills they need
to develop. Please adjust and use these plans as you
would like
or
toss them in the trash 

2. Grade 2 ~ Back To School Formative Assessments
Time Line: August 4 – August 8, 2014
CCSSM:Operations and Algebraic Thinking
2.OA.1. Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of
adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using
drawings and equations with a symbol for the unknown number to represent the problem.
Number and Operation in Base Ten
2.NBT.5. Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or
the relationship between addition and subtraction.
Mathematical Practices
#7-Make sense of problems and preserve in solving them.
Learning Targets
*I can choose when to use addition or subtraction in a word problem.
*I can represent addition or subtraction word problems using objects, drawings, and equations with unknowns in all
positions.
*I can add and subtract numbers within 100 with ease by applying strategies (decomposing numbers into tens and ones,
using commutative and associative properties) based on the numbers being added subtracted.
Vocabulary
review words from first grade vocabulary for math add in task and craftivity
Math Tools
various counting tools as well as 120 chart and red/yellow counters

Procedures and Formative Assessment
If You Take a Mouse to School – read story or listen to video of story. Discuss and allow students to work on activity sheets
that go along with story to pre-assess math skills. As students are working on sheets, meet with individuals or small groups to
do more assessment of skills such as adding to 10, subtraction to 10, place value knowledge, etc.

Procedures and Formative Assessment
Giraffes Can’t Dance Math Task – read story or listen to video of story and discuss thoughts about math and how different
people solve things and see things in different ways. Create a Gerald Giraffe and have student begin to solve the problems
using red/yellow chips…discuss how different people had different answers and talk about accountable talk.

Giraffes Can’t Dance Math Task –continue with Gerald’s craftivity and tasks…students can create a Gerald to hang in
hall…variations of how the finished product will look are acceptable.

4. Gerald the Giraffe
Math Tasks
After reading the book,
“Giraffes Can’t Dance”
by Giles Andreae,
students complete a craftivity
of Gerald that will help them
solve math tasks.HSamuelson

5. Create Gerald the Giraffe and
manipulate the circle and triangle
cut outs on Gerald’s body. Show
and discuss solutions to different
problems that are projected to read
or read outloud.
The last math story is a math task
that has the kids creating ten spots
on Gerald’s body using the circle
and triangle cut outs… (Great for
composing and decomposing
concepts>)
Students use the D.E.W. to solve
the math task as a way of
practicing for the CRAs in the
future…Draw a model, write an
Equation and Write an explanation
of how they got their answer as
well as describe how they know it

6. To prepare for this
Craftivity, you’ll need to
pre-cut the giraffe’s body
from yellow paper. You
can also choose to
create templates of the
giraffe’s body for the
kids to trace and cut out
on their own.
Each child will need 10
circles and 10 triangles
(both about the size of a
quarter). I like to pre-cut
the circles and triangle
for continuity in size and
shape. However, you

42. Use dominoes during the
first lesson to create a
station that can last all
quarter…dominoes can
be used to create
addition and subtraction
sentences as well as to
search for a certain sum
on a domino and record
the different choice.
