Grade 2

Frog Unit        3 wks

Math Lesson 1 (Ties: Music, ELA)              1 hr lesson (approx.)


Previous Knowledge:

-         students will have had experience in counting by twos and fours

-         student will have had experience using Body Percussion & 4 beat ostinati



PR – II.1.2 Identifies, creates, extends, describes, and compares both numerical and non-numerical patterns

PR – III.1.2 Translates patterns from one mode to another, including concrete, pictorial,charted, spoken, written, and those patterns generated using technology

SP – III.1.2 Organizes data independently, using graphic organizers as diagrams, charts, and lists

N-V.1.2 Uses manipulatives, diagrams, and symbols to demonstrate and to describe multiple strategies for determining sums and differences of numbers to 100, with and without regrouping




            1. Chant, read and play simple rhythmic ostinati in duple, and triple meters

            2. Verse-Refrain

            3. Body Percussion


3.3.1 Categorize related information and ideas using a variety of strategies [such as  linking significant details, sequencing events in a logical order…]



-         large free space (enough to make a whole class circle)

-         8 x 14 paper (1 for each student)

-         “Frog Song” (from An Orff Mosaic from Canada, ed. by Birkenshaw-Fleming)


Activating Strategies:

-         teach “Frog Song” by rote (patch-clap on beat)


Acquiring Strategies:

-         ask 1 student to hop into the pond (middle of circle)

-         how many frogs are in the pond? (1)

-         how many eyes are in the pond? (2)

-         how many legs are in the pond? (4)

-         chant “1 frog, 2 eyes, 4 legs, kerplunk, in the pond!” with BP

-         sing “Frog Song” – another frog jumps into pond on “ribbit”

-         how many frogs are in the pond? (2) Eyes? (4), Legs? (8)

-         chant “2 frogs, 4 eyes, 8 legs, kerplunk, in the pond!” with BP

-         sing “Frog Song”, adding a third frog on “ribbit”

-         continue until 5 frogs are in the pond, and then clear the pond

-         restart with new students until all students have had a turn in the middle

-         try chanting without counting in advance – keep the rhythm going


Applying Strategies:

-         divide an 8 x 11 paper into 5 columns

-         draw a frog at the top of each column*

-         under the frog in the first column, write:        1 Frog

                                                                                    2 Eyes

                                                                                    4 Legs

            -     students make their own chars and fill in the blanks for remaining columns

* draw 1 frog in each column, or 1 frog in column 1, 2 frogs in column 2, etc.


Follow Up/Extension Ideas:

For a challenge:

-         play the game and try adding 2 frogs at a time

-         do the chant in “concentration” style – each student says one part, trying not to break the rhythm:

                        Student A: 1 Frog

                        Student B: 2 Eyes

                        Student C: 4 Legs

                        Student D: 2 Frogs

                        Student E: 4 Eyes


-         play game again, going past 5 frogs in the pond (how high can they get?!)

-         try subtracting frogs from the pond

-         instead of using students as frogs, use felt frogs, stuffed frogs, frog ornaments, etc.)



Can be done at many different levels:


            1) When playing game, ask students to close their eyes and hold up fingers – this can only be done for the first 2 frogs, as they will run out of fingers!!

            2) When playing game, ask individual students for answers

            3) Students’ frog chants can be assessed as a class or as individuals – do they have the right numbers?  Do they know the patterns?

            4) Pick a different type of animal or insect – maybe something with 2 legs or 6 legs.  Can the students transfer what they have learned in the previous activity to a different set of number patterns?

            5) Completed Frog Column activities can be assessed for understanding



            5) Watch students during game/song for beat competency and correct BP ostinato pattern


Personal Assessment:

-         the lesson worked well – students enjoyed the game and were very ready and enthusiastic to give answers

-         the activity was engaging enough to allow each student a turn in the “pond” without becoming boring

-         there were a lot of activities that would be meaningful follow-up exercises

-         the written work (chart) was the grade 2 teacher’s idea, and I thought it was an awesome extension/assessment idea!!
