    • Warming Up (10 minutes)

    Ask students to play an online game (Link 1) where they have to guess the standard form of the number from the given word form. The game will be a warm up for the students where each student can choose the level that fits his/her abilities, and you can ask, for example, grade 1 to choose level 1-10, grade 2 level 1-20, and grade 3 1-100 and 1-1000.

    Have students give feedback on his/her answers immediately then share a screenshot of the score with you.

    • Learning Activity 1 (20 minutes)

    After remembering and practicing numbers in word form, send a short YouTube video (Video 1) that explains the meaning of standard and expanded form and gives several examples on how to convert a number from standard to expanded form. The explanation is mainly based on place value lessons that the students already mastered.

    In the video the students will see how to convert from standard form to expanded form and the opposite as well. To further practice transforming a number from the standard form, have students play a game. Send Link 2 and direct them to answer and play.

    To check for understanding, send the following question and asks students to reply with voice notes: How can we change an expanded form of a number into the standard form using place value and addition method?

    • Learning Activity 2 (15 minutes)

    Now, after practicing and addressing the objectives of the lesson, have students work independently and answer questions on the lesson prepared by the teacher using Link 5. Have them enter, insert their names, and solve all the questions. The game is in a form of questions and they can earn “dollars” on every correct answer, and will lose “dollars” on every wrong answer.

    To check for understanding, you will receive the results on the website when students finish playing so that you can check and observe their progress and understanding of the lesson.

    • Wrap-Up (5 minutes)

    You can send a voice note on Whatsapp or create a small PowerPoint or any other document depending on the platform your school is using, summarizing the main ideas of the lesson: defining the standard form, word form and expanded form meaning, emphasizing how we can convert from each form to the other starting from the place value of the numbers, and reminding the students of how addition can help in expanded form. Have students share their questions via Whatsapp or the used platform.

    For homework, send students Link 3 and Link 4. Have students send a screenshot of the results to you.

    For the assessment, use Link 6 and the rubric (Answer Key 1).
