Mr. Marwan explains to his students that today's lesson will take place outside the classroom, as they will visit local stores to learn about measuring everyday products. He assigns each group a different location, such as the school canteen, a minimarket, and a grocery store. The students are excited and begin planning their group roles, with specific members taking responsibility as group leaders, note-takers, and presenters. This approach brings practical numeracy applications into everyday situations.
đ Applying Measurement Concepts
In response to a student's question, Mr. Marwan reviews last week's lesson on basic and derived units of measurement. He asks the class to recall how they measured various items like body mass, water volume, and temperature. The lesson's goal is to help students observe and compare product sizes and measurements in real-world settings. A student provides an example involving different milk package sizes, sparking a discussion on product quantity and packaging. Mr. Marwan encourages students to explore similar scenarios during their upcoming activity.
đ Practical Numeracy at the Stores
The students, now in their assigned groups, visit local stores to explore and compare the sizes of various products. Each group has a specific assignment: for example, one group is tasked with finding detergent and cooking oil in different package sizes. Students use their knowledge from the lesson to determine the mass of these products and identify the correct measurement units. The activity emphasizes the practical use of numeracy by comparing quantities, applying algebraic concepts, and understanding unit conversions, all while working collaboratively.
đĄ Problem-Solving Through Unit Conversion
During the store visit, the students apply their numeracy skills to real-life questions, such as determining how many 500g packages of detergent are needed to make 4kg. By converting between grams and kilograms, students strengthen their understanding of mass and algebra. They also compare the costs of purchasing in different quantities. The activity allows students to discover that larger packages are often more cost-effective, fostering critical thinking and problem-solving skills.
đŹ Presenting and Reflecting on the Experience
As the groups finish their tasks, they return to class to present their findings. Each group discusses the products they measured and compared, focusing on both the numeracy aspects and real-world relevance. The presentation provides an opportunity for peer feedback and further reinforces their understanding of measurement concepts. The lesson concludes with a reflection on how numeracy can be integrated into subjects beyond mathematics, highlighting the importance of diverse group dynamics and clear role distribution to ensure effective teamwork.

banyak yang berpendapat bahwa hanya guru
matematika lah yang bertanggung jawab
dalam menaikkan kemampuan numerasi
peserta didik padahal numerasi itu bisa
loh dilakukan di semua mata pelajaran
Yuk kita lihat salah satu contohnya Pak
Marwan adalah guru kelas 7 saat ini
ingin mencoba untuk meningkatkan
kemampuan numerasi peserta didik melalui
mata pelajaran IPA materi penguatan
konsep pengukuran besaran pokok dan
besaran turunan
Pak Marwan ingin sekali mengajak peserta
didiknya untuk dapat menerapkan konsep
ini dalam kehidupan sehari-hari
sekaligus dapat menguatkan kemampuan
numerasi mereka
saat ini Pak Marwan ingin peserta
didiknya bekerja dalam kelompok Mari
kita menuju SMP cita Jaya hari ini Pak
Marwan memberitahukan kepada peserta
didik bahwa jam IPA kali ini akan
digunakan untuk belajar ukuran
barang-barang kebutuhan dengan datang ke
tokonya langsung yang tentu saja
disambut dengan antusias lalu Pak Marwan
membagi peserta didik menjadi beberapa
kelompok
[Musik]
jangan lupa silahkan menentukan siapa
yang bertindak sebagai ketua kelompok
notulen dan siapa yang akan presentasi
nanti di kelas untuk masing-masing
kelompok ya
Baik Pak setiap kelompok telah
ditentukan tempat yang harus kalian
datangi kelompok 1 silahkan menuju ke
kantin sekolah kelompok 2 akan
berkunjung ke minimarket di samping
sekolah kelompok 3 silahkan menuju toko
sembako Bu Minah seberang sekolah
Maaf Pak izin bertanya apa yang akan
kami lakukan di sana
baik Henry Minggu lalu kita sudah
mempelajari Pengukuran besaran pokok dan
besaran turunan Ayo Adakah yang masih
ingat apa yang kita lakukan Minggu lalu
mengukur massa badan mengukur suhu tubuh
kita dengan termometer
mengukur volume air dengan gelas ukur
Bagus ternyata masih ingat Sekarang kita
akan mencoba menerapkan pengukuran itu
dalam kegiatan kita sehari-hari
seringkali kita menemukan berbagai
produk kebutuhan dalam berbagai ukuran
ada yang pernah memperhatikan Ayo
Seperti apa contohnya saya sering
memperhatikan Ibu membelikan adik susu
kadang dalam kemasan besar juga sering
dalam kemasan lebih kecil mungkin
kemasan lebih besar isinya lebih banyak
Wah tepat sekali Nah jadi kegiatan kali
ini adalah menentukan ukuran dari
beberapa produk kebutuhan sehari-hari
dan membandingkan harganya ya ini ada
panduan lengkapnya di Lembar kerja yang
akan Bapak bagikan
Wah pagi hari yang sibuk Pak Marwan
merasa semua sudah siap dan
mempersilahkan peserta didik untuk
belajar di tempat yang sudah ditentukan
peserta didik menuju toko dan mencari
produk yang sudah ditentukan di LK
masing-masing kelompok misalnya kelompok
2 akan ditugaskan di minimarket seberang
sekolah dan mencari produk deterjen dan
minyak goreng berbagai kemasan
sedangkan kelompok lain mencari produk
susu minuman segar gula berbagai ukuran
shampo dan sabun dengan merk tertentu
dalam berbagai ukuran serta
bermacam-macam produk kebutuhan lainnya
sebelum mulai Mari kita pahami lembar
kerja dulu ya teman-teman
[Musik]
Wah dari lembar kerja terlihat bahwa
kegiatan ini melatih pemahaman peserta
didik Pada topik besaran pokok massa
deterjen dan konversinya sekaligus
sebagai penguatan aljabar Coba kita
kembali pada ilustrasi berikut ini
Ayo kita cari deterjen
ini deterjen Iya betul dan ini Ada
kemasan deterjen 2 kg dan 500 gram di
Lembar kerja ditanyakan ini besaran
pokok apa dan alat ukurnya Ayo itu tulis
besaran pokok massa berarti alat ukurnya
timbangan
kegiatan ini melatih pemahaman yaitu
mengetahui ukuran 500 gram dan kemasan 2
kg adalah ukuran untuk besaran massa dan
alat ukurnya baik kita lanjutkan
ibu kami butuh 4 Kg deterjen eh berapa
kemasan deterjen 500 gram yang harus
dibeli ya untuk mendapatkan deterjen
sebanyak 4 Kg
1 kg = 1000 gram jadi untuk 4 Kg akan
membutuhkan 8 kemasan deterjen 500 gram
aku bener nggak ya
kegiatan ini melatih penerapan yaitu
menghitung harga dalam kemasan 500 gram
dan membandingkan dengan harga kemasan 2
kg
berapa kemasan deterjen 2 kg yang harus
dibeli untuk mendapatkan deterjen
sebanyak 4 Kg 2 bungkus Wow Oke Oke
selanjutnya Berapa harga 4 Kg deterjen
jika membeli dalam kemasan 500 gram
bandingkan harga deterjen jika membeli
kemasan 2 kg
di sini harga 500 gram tertulis 8000
kita butuh 8 bungkus berarti 8 x 8000 =
64.000 sedangkan harga kemasan 2 kg
deterjen adalah 28.000 untung 4 Kg kita
harus beli 2 bungkus harganya
2x28.000 yang jadinya 56.000 benarkan Oh
ternyata kemasan 2 kg lebih murah 8.000
Ayo sekarang kita cari minyak goreng
waktu tinggal 20 menit lagi sebelum
kembali ke sekolah kegiatan ini melatih
penalaran peserta didik untuk mengambil
kesimpulan bahwa kemasan 2 kg lebih
murah dan dengan membeli deterjen
kemasan 2 kg akan menghemat sebesar 8000
rupiah
ibu dan bapak ternyata dengan
membandingkan produk-produk yang
ukurannya berbeda-beda bisa meningkatkan
kemampuan numerasi dan memahami konsep
besaran turunan misalnya dalam bentuk
gram dan kilogram juga liter dan ML
Sebelum kelas berakhir Pak Marwan
mengajak tiap kelompok untuk
mempresentasikan hasil kelompoknya di
depan kelas dengan begini mereka bisa
saling mendapatkan umpan balik tahapan
diskusi kelompok dapat melatih peserta
didik untuk mengomunikasikan
pemahamannya pada orang lain bagaimana
ibu dan bapak benarkan Ternyata numerasi
bukan hanya dapat dibangun melalui
pelajaran matematika Contoh aktivitas
yang dilakukan peserta didik tadi bukan
saja mengajak mereka terbiasa dengan
angka tetapi melatih mereka untuk
menerapkan dalam kehidupan sehari-hari
yang perlu diperhatikan saat pembuatan
aktivitas generasi dalam kelompok adalah
letakkanlah kemampuan murid dan bagilah
kelompok sesuai dengan kemampuan murid
yang beragam Sehingga masing-masing
peserta didik dapat saling bantu
yang kedua pastikan tugas masing-masing
anggota kelompok sudah jelas jangan lupa
untuk melibatkan murid saat pembagian
peran untuk bisa melaksanakan kegiatan
dengan baik
misal setelah ditukar bersama putri
berperan menjadi notulis Henry berperan
menjadi juru bicara saat presentasi Misa
berperan menjadi ketua dan lain-lain
sekian materi kali ini semoga dapat
memberikan inspirasi aktivitas membatasi
di mata pelajaran ibu dan bapak sudah
siap melihat inspirasi berikutnya Yuk
kita lihat video selanjutnya
