Kindergarten- Students matched dominoes up with the appropriate numeral. We did some problem solving using patterns. We also did Number Talks using different dot patterns for 4.
Thank you so much to everyone who has sent in supplies! They just show up in my room so I am not sure who to thank so I hope all the donors read this :-)
Kindergarten- Students worked with a partner to put pony beads on a pipe cleaner to match different numerals. This helped their number sense and their fine motor skills :-)The students enjoyed this and all materials can be found in the crafting section at Walmart for under $5. We also did some problem solving using patterns.
1st Grade- The first graders are blowing me away with the things they come up with in number talks! We had a ten-frame scavenger hunt to work on subitizing. We also did some problem solving using addition and subtraction.
2nd & 3rd Grade- We used a 100s chart to help us use the count on by 1 strategy with bigger numbers. We also used a graphic organizer to write constructed responses about the problems we solved last week.
4th & 5th Grade- We used a 0-200 number line to help us skip count by 10s and 5s by various numbers to help the students see it would always take twice as many jumps when we count by 5s. The activity really helped students understand why "Solving 5 facts using your 10 facts" works. Students completed a chart that also helped them use this strategy and see that the product of a number multiplied by 5 will always be half if that same factor is multiplied by 10. We also used a graphic organizer to help us write constructed responses about the problem we had solved in the previous lesson.
We are using the Singapore Bar Model Drawing model for problem solving in Math Lab. There is an interactive activity on Math Playground (and an app version) called Thinking Blocks. If your child could spend some time on this interactive activity at home, it would help them with problem solving and what we are doing in the lab. They will have some time in Computer Lab one day soon to work on this website too.
We were able to get so much done this week in Math Lab. Every grade level did some number sense and/or basic fact strategy practice and were introduced to the Singapore Bar Model Drawing strategy.
Kindergarten: We worked on subitizing (ability to see a small amount of objects and know how many there are without counting) using dot cards. We also did some visual problem solving that compared amounts. The students sang a song that let them exercise while writing numbers in the air and a song about the days of the week. The students were given either a number or a dot card and they had to find their match and share with the class.
1st Grade: We worked on subitizing using five-frames. They did visual problem solving that involved making an estimate based on a benchmark. The students sang and exercised to a song where they counted by 2s. The students got to go on a scavenger hunt for 5 Frames and write addition sentences to match them.
2nd Grade & 3rd Grade: We reviewed vocabulary words that go with addition facts (addends and sum). We played a game to practice the strategy of adding one more in addition facts. I introduced them to Model Drawing for problem solving and we did 2 problems together that involved addition.
4th & 5th Grade: We worked on our 5 facts with the strategy of Using Ten Facts. It is great for facts like 24 X 5. The kids can do 24X10=240 in their head and then split 240 in half to get the answer of 120. They played a game to work on their 5 facts. I introduced them to model drawing and we did 2 problems together that involved multiplication.
We had a great second week in the Math Lab. We finished up our "Lewis' Mathematician" wall for lesson #2. Some students came for lesson #3 yesterday and today, everyone else will have lesson #3 on Monday or Tuesday. For lesson 3 we worked on different things according to the grade level. All grade levels did a little bit of "Number Talks".
Kindergarten- we looked at identifying numbers on dot cards and they created their own dot card to show the value of 3. We also did a couple visual problem solving problems. We sang and danced to a song to practice counting to 20 and another one to practice days of the week.
1st Grade- We looked at seeing numbers on a 5 frame. We discussed different ways to represent the same number. They also solved a couple visual problems. They each got to manipulate 5 counters to represent different basic facts that equal 5. We sang and exercised to a song where we count by fives.
2nd Grade- We took an addition pretest so that we can start working on our strategies for memorizing our addition facts next time. We watched a sing a long video on YouTube to help us learn the words addend and sum. We discussed the vocabulary words from the video. Students brainstormed a list of addition being used in the real world.
3rd Grade- We took a multiplication fact pretest so the students can see how much they grow between now and the end of the year. We learned about arrays and added the words horizontal to rows and vertical to columns. We watched a video where we saw lots of real life examples of arrays represented as repeated addition. Students made various arrays for a given number.
4th Grade & 5th Grade- We took a multiplication fact pretest so that students can track how they grow over the school year. I introduced them to the strategy of using ten facts for 5 facts. This is a great mental math strategy for bigger facts like 24X5. You can think 24X10=240 and half of 240 is 120 so 24X5 is 120.
