Lucia counting 10 eggs in one row. Then she counted in 10s across the top. She found out there were 120.
ReplyDeleteThen I saw that there were 12 rows across and 10 rows down. That make 120 eggs.
'I learnt how to count in my 10s to answer this question'
DeleteSienna saw the eggs divided into four equal groups. She knows four equal groups makes the whole. Sienna counted 24 eggs in one quarter. So she added 24 + 24 + 24 + 24 = 96.
ReplyDeleteSienna checked and counted in 5's and counted more than 96. So she thought there were 6 groups of 5 not 4. So the answer is 30 in each quarter. And 4 groups of 30 is 120.
Delete"I learnt it is OK to get something wrong, because I could work out the correct answer and learn from it'
DeleteJackson also saw the eggs divided into 4 equal groups. He counted 6 eggs across and 5 eggs down in each quarter. That means 6 groups of 5. This equals 30. Then he counted 4 groups of 30.
ReplyDelete30 + 30 + 30 + 30 = 120. Jackson added on 30 each time.
" I learnt to add in 10s and that the ones don't change. eg. 42 + 20 = 62"
DeleteAlexander used the place value blocks. He saw each row had 10 eggs, so he used the tens blocks. He put 12 groups of ten together. 12 groups of 10 equals 120.
ReplyDelete12 x 10 = 120
"I learnt that 10 ones MUST be swapped for one 10 block'
Delete"We learnt to count in 10s" "We know 12 groups of 10 are 120" 12 X 10 = 120. Kakariki Group
ReplyDeleteRaphael found out that there were 6 eggs across and 5 down in each square. He then went 5 x 6 and found that too tricky so he swapped it around and said 6 x 5. He knew 6 x 5 = 30. He then added 30 + 30 = 60, and 6 + 3 = 9 so 60 + 30 = 90 and then it turned to 100 plus one more 10 makes 120.
