Description
Welcome to the BEST subitizing practice EVER! Subitizing is the immediate recognition of a quantity. It builds number sense and strengthens knowledge of number facts with meaning, not just memorization. Included are slides with various ten frames, tally marks, fingers, dominoes, and dice.
• Let your students see the slide as you say the word “subitize” to yourself. Then advance to the next “Get Ready!” slide. Ask students who know how many to raise their hands.
• After a student answers correctly, ask, “How did you know that?” Encourage students to use strategies such as counting on, grouping, and how many are missing. On many slides you can also ask students what addition fact is represented as well as the final quantity.
• Subitize whenever you have spare seconds! Even if you only have a minute, your students can benefit from these mental math exercises AND mini-number talks (How did you arrive at your answer?).
