Comments
Martin Discher
yes
yes
tiles building up 11+11=22 22+22=44
11+11=22 22+22=44
direct modeled with tiles, said he counted all, but the tiles allowed him to see how the
groups of 11 build up
Shuhrat Suhana
yes
yes
straws & drew circles (counted on from 11)
number sentence attempt to build up
X 21+21=43
accidentally drew 12 circles in second row instead of 11, dots
inside circles shows her counting each circle (probably didn’t count on), may have known she could double the
21 to find the answer but didn’t know how to add 21+21 so
counted all
Aaron Pogarsky
yes
yes
straws & drew circles
building up 11+11=21 21+21=42
X 21+21=42
represented problem correctly, not sure if mistake is result of counting error or attempt to add 11+11 mentally, solved 21+21 without counting
because he likely would have gotten a different answer (like
Shuhrat)
Eleanor Shi
yes
yes
drew circles
wrote number sentence
as repeated addition of
10s
decomposed into 10s and 1s
10+10+10+10+4=44
decomposed 11 into 10s and 1s, drew circles on paper, dots
on first row indicate she started counting all but absence of dots on
subsequent rows indicate she stopped counting, also only drew 9 circles in one row,
further supporting the idea that she was not counting circles
Jeffrey Sanzari
yes
yes
drew seed packets
and seeds (counted on from 11)
wrote his number sentence
as repeated addition
11+11+11+11=44
said he counted on fingers, but dots on paper indicate he counted circles on paper,
labeled his drawing with 11s written above his groups,
demonstrated understanding of repeated addition with
number sentence
Emma Samedi
yes
yes
cubes & drew seeds
number sentence almost reflects
building up strategy OR
attempt to show
repeated addition
X 11+11=22 11+11=44 almost
building up
didn’t group illustration of seeds in any way on her paper, probably counted cubes and not illustrated
seeds because there aren’t dots on her paper, didn’t know how to represent the repeated addition (or possibly building up) via number sentence
