A sk: How many hands do you see? 3. S ay: 1 - mi ne (pointing to your hand) and 2- he r s/hi s (pointing to the student’s hand). 1 + 2 = 3 . S ay: Did you notice we did not count the hands individually. We grouped it as 1 (mine) and 2 (student’s) and then added them together to reach 3. Ask another student to join you and let him/her raise both their hands. A sk: How many hands do you see? 5. S ay: Remember, we already counted up to 3 (pointing to your hand and the first student’s hand) and now we have to c o unt 2 mo r e (point to the second student’s hands). 3 + 2 = 5 . S ay: Again, we did not count the hands separately, but added 2 (second student’s hands) as a group to the previous number “3”. Ask yet another student to join you and ask her/him to raise just one hand. A sk: How many hands do you see? 6. S ay: We already had already counted up to 5 (point to your hand, first student’s and the second student’s hand) and now, we need to Copyright 2015 www.matific.com 3 c o unt 1 (pointing to the third student’s hand). 5 + 1 = 6. S ay: Here, each time while counting on, we added the next group instead of individual numbers. We count in one's or in two's depending on the group. T e ac he r pr e se nt s M at h game : F l yi ng F l o c ks - A dd up t o 10 | 8 min Present Matific’s episode F ly in g F lo c k s - A d d u p t o 1 0 to the class, using the projector or interactive whiteboard. The goal of the episode is to learn and practice counting in relation to addition ranging from 1 - 10. The birds fly, one by one or in pairs, in short intervals. The task is to count the passing birds. The student is required to adjust his or her counting to the number of birds crossing: count in one's when one bird crosses, and two's when 2 birds cross. That trains the student to relate counting to addition of quantities, and understand how addition questions can be solved by forward counting. Copyright 2015 www.matific.com 4 S ay : In this game we have to count the number of birds flying. They may fly in Ones,Twos, or even Threes. We need to count on in Ones, when one bird flies, and in Twos if two birds fly together. As soon as I press the button, the birds will begin to fly across the screen. Are you ready to count with me? Press the button. Count the birds along with the students, aloud. A sk: How many birds did you see? 2 birds. 1 bird flew first and another one followed. One plus one is two (1+1=2). Click on box “2”. A new screen will open up. Press the button when ready to count. Copyright 2015 www.matific.com 5 Twice, the birds fly in two’s. Count them aloud along with the students. “Two plus two four” (2+2=4) A sk: How many birds did you see? 4 birds. 2 birds flew together at first and another pair followed. S ay: Notice that we counted in two’s this time. Click on box “4”. A new screen will appear. S ay : Another way to count is when the birds fly, put up equal numbers of fingers and later count the fingers. Use this to check your own answer. Let us use it in the next set. Press the eye button. Count 1 when the first bird flies and at the same time put 1 finger up. Two birds fly next. Put 2 more fingers up and count 3. Two more birds fly next so put 2 more fingers up and count 5. One bird flies next. Count 6 and put up 1 more finger. A sk : How many birds did we count? 6 birds. Say: Let us count the fingers. 6. Click on box “6” The next screen shows that when a wrong answer is given, Matific counts the birds explicitly and displays the number on the screen during the counting sequence. Copyright 2015 www.matific.com 6 S ay : Let us count the birds silently and try not to use the fingers. A sk : How many birds did you see? You will get various answers. S ay : Let us check our answer. My answer is 9 (incorrect answer). Please count out aloud, along with the screen. Input 9. The screen will show counting sequence while displaying correct numbers. S ay : The correct answer is 10. Complete all sets so that students will get to know the process better. Encourage students to count mentally, without using their fingers. Note: The birds start flying on screen almost immediately when you hit the “ready” button, so prepare students to be prepared to begin counting before hitting the button. S t ude nt s pr ac t i c e M at h game : F l yi ng F l o c ks - A dd up t o 10 | 15 min Have the students play Matific’s episode F ly in g F lo c k s - A d d u p t o 1 0 on their personal devices. Circulate, answering questions as necessary. In the event that some students finish playing the Matific’s episode F ly in g F lo c k s - A d d u p t o 1 0 , encourage students to play Matific’s episode F ly in g F lo c k s - A d d u p t o 2 0 helping them with their difficulties, if any. Copyright 2015 www.matific.com 7 C l ass di sc ussi o n | 10 min A sk : In the game, why do you think, we counted the birds in 1s and in 2s depending on the number of birds flying together? While counting a large number of objects, it is faster to count in groups. So, while counting the birds which flew in pairs we counted in 2s instead of counting them individually. Counting becomes easier this way. When two birds are flying together, we count them visually as a picture and not count them separately. We “know” by looking at the picture that there are 2 birds and we do not have to count each one. Display the following on board. A sk : How many cherries can you see? 9. 1 + 2 + 2 + 1 + 1 + 2 or 1, 3, 5, 6, 7, 9 S ay : Another way would be to count all the cherries in pairs first and then add all the individual cherries. 2 + 2 + 2 + 1 + 1 + 1. or 2, 4, 6, 7, 8, 9 A sk : What other method can you use to count these? Counting all the cherries individually. Copyright 2015 www.matific.com 8 C l o si ng | 4 min A sk : What did we learn today? We learned to count by addition in 2s or 1s, depending on the situation. Present Matific’s episode F ly in g F lo c k s - A d d u p t o 2 0 to the class, using the projector or interactive whiteboard in a preset mode. Play the first game and encourage students to give you the answer. Ask students to play this game as homework. Copyright 2015 www.matific.com
